    Description / Table of Contents: New Azide Bridged d-Transition Metal ComplexesThe azide bridged cations [(diphos)Ni(N3)2Ni(diphos)]2+, [Ph3P)2(CO)MN3M(CO)(PPh3)2]+ are obtained from the monomeric azido complexes (diphos)Ni(N3)2 and (Ph3P)2M(CO)N3 (M = Rh, Ir) respectively with nitrosyl and triethyloxonium salts. In the rhodium- and iridium(I)compounds, accessible also from (Ph3P)2M(CO)N3 and [(Ph3P)2M(CO)(NH2CO2Et)]+ BF4-, two transition metal atoms are bridged by only one azide ligand.
    Notes: Die azidverbrückten Kationen [(diphos)Ni(N3)2Ni(diphos)]2+, [Ph3P)2(CO)MN3M(CO)-(PPh3)2]+werden aus den monomeren Azido-Komplexen(diphos)Ni(N3) 2bzw.(Ph3P)2M(CO)N3 (M = Rh, Ir) mit Nitrosyl- oder Triäthyloxoniumsalzen erhalten. In den Rhodium- und Iridium(I)-Verbindungen, die auch aus (Ph3P)2M(CO)N3 und [(Ph3P)2M(CO)(NH2CO2Ät)]+ BF4- zugänglich sind, werden zwei Übergangsmetallatome nur über eine N3-Gruppe verbunden.

    Description / Table of Contents: Reactions of trans-Difulminatobis(triphenylphosphine)platinum(II)The thermally very stable fulminato complex (Ph3P)2Pt(CNO)2 (1) rearranges under mild conditions to the isomeric isocyanato complex (Ph3P)2Pt(NCO)2 in the presence of organic carbonyl compounds which act as catalysts. (Ph3P)2Pt(NCS)2 is obtained from 1 and organic thiocarbonyl compounds. 1 is reduced by phosphines to the corresponding cyanide trans-(Ph3P)2Pt(CN)2. The safe preparation of a number of fulminato complexes (R3E)2M(CNO)2 (M=Pd, Pt; E=P, As, sb), (Ph3P)2Pt(X)CNO (X + H, Me, CN, NCO), and (Ph3P)2Rh(CO)CNO by use of [AsPh4]CNO is reported.
    Notes: Das thermisch sehr stabile (PhP)2Pt(CNO)2 (1) läßt sich katalytisch in Gegenwart von organischen Carbonylverbindungen unter milden Bedingungen zur Isocyanatoverbindungen (Ph3P)2Pt(NCO) 2 isomerisieren. 1 liefert mit organischen Thiocarbonylverbindungen (Ph3P)2Pt(NCS)2. Mit Phosphinen wird 1 zur entsprechenden Cyanoverbindung trans-(Ph3P)2Pt(CN)2 reduziert. Über die gefahrlose Darstellung verschiedener gemischter Fulminatokomplexe (R3E)2M(CNO)2 (M=Pd, Pt; E=P, As, Sb), (Ph3P)2Pt(X)CNO (X=H, Me, CN, NCO) und (Ph3P)2Rh(CO)CNO unter Verwendung von [AsPh 4]CNO wird berichtet.

    Description / Table of Contents: Platinum as an Amino Protecting Group: Platinum (IV) Complexes with α-Aminoacyl ChloridesChlorination of the (α-amino acid)platinum(II) compounds trans- Cl2Pt(NH2CHRCO2H)2 and Cl2Pt(NH2CH(CO2H)CH2CH2SR) by PCl5 leads to the (aminoacyl chloride)platinum(IV) complexes 1 and 2. The oxidative addition of the coordinated N-protected amino acyl chloride in 1 and 2 to the platinum(0) compound (C2H4)Pt(PPh3)2 affords the chloro-α-aminoacyl complexes 3 and 6, respectively.

    Description / Table of Contents: Reactions of Coordinated Isocyanate Ligands Protonation and Carbonylation of Planar Isocyanato d8-Metal Complexes in the Presence of AlcoholsThe isocyanato complexes (Ph3P)2M(CO)NCO (1a M == Rh; 1b M == Ir) react with HBF4 and ethanol to give carbamic ester complexes 2a and b, which are deprotonated by NaOEt to ethoxycarbonylamido complexes 3a and b. On heating 1a and b are formed from 3a and b. Reaction of (Ph3P)2M(NCO)2 (M == Pd, Pt) with HBF4 and EtOH yields [(Ph3P)2Pd(NH2CO2Et)](BF4)2 and [(Ph3P)2Pt(NHCO2Et)2Pt(PPh3)2](BF4)2. By carbonylation in methanol 3a and b are converted to alkoxycarbonyl complexes (Ph3P)2M(CO)2CO2Me (M == Rh, Ir). Reaction of [(Ph3P)2Pt(CO)CO2Me]BF4 with NaO Me affords trans-(Ph3P)2Pt(CO2Me)2. I.r., n.m.r., and dipole moments of the compounds are reported.
    Notes: Die Isocyanatokomplexe (Ph3P)2M(CO)NCO (1a M == Rh; 1b M == Ir) setzen sich mit HBF4 und äthanol zu Carbamidsäureester-Komplexen 2a und b um. Diese werden mit NaOät zu Äthoxycarbonylamido-Verbindungen 3a und b deprotoniert, die bei der Thermolyse wieder in 1a, b übergehen. Bei entsprechenden Reaktionen der Palladium- und Platinkomplexe (Ph3P)2M(NCO)2 mit HBF4 und ÄtOH werden die Verbindungen [(Ph3P)2Pd-(NH2CO2Ät)](BF4)2 und [(Ph3P)2Pt(NHCO2Ät)2Pt(PPh3)2](BF4)2 isoliert. Die Carbonylierung von 3a und b in Methanol führt zu den Alkoxycarbonyl-Komplexen (Ph3P)2M(CO)2CO2Me (M == Rh, Ir). Durch Umsetzung von [(Ph3P)2Pt(CO)CO2Me]BF4 mit NaOMe wird trans-(Ph3P)2Pt(CO2Me)2 erhalten.  -  IR- und NMR-Spektren sowie Dipolmomente der Verbindungen werden mitgeteilt.

    Description / Table of Contents: n.m.r. Investigations on Boron Compounds, IV. 14N-n.m.r. Studies on Simple Amino BoranesChemical shift data δ14N and line width at half peak height for a considerable number of amino boranes of the types B(NR2)3, B(NHR)3, R'B(NR2)2, R'B(NHR)2, R'2BNR2, R2'BNHR, R2BNH2, (R2'B)2NR, some hydrazino boranes and dialkylamino halogeno boranes are reported and discussed in connection with the δ11B data of these compounds. A decrease in shielding of the 14N nucleus is observed with increasing BN bond order. Neighbour anisotropy effects as exerted by the heavier halogens add to this trend in the shielding.
    Notes: Chemische Verschiebungen δ14N und Halbhöhenbreiten zahlreicher Amino-borane des Typs B(NR2)3, B(NHR)3, R'B(NR2)2, R'B(NHR)2, R'2BNR2, R2'BNHR, R2BNH2, (R2'B)2NR sowie einiger Hydrazinoborane und Dialkylamino-halogenborane werden mitgeteilt und im Zusammenhang mit δ11B-Werten vergleichend diskutiert. Es ergibt sich eine mit zunehmender BN-Bindungsordnung fallende Abschirmung des 14N-Kernes. Nachbargruppen-Anisotropie-effekte, insbesondere der schweren Halogene, verstärken diesen Trend.
