    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.
    Notes: Durch Chlorierung der (α-Aminosäure)platin(II)-Verbindungen trans-Cl2Pt(NH2CHRCO2H)2 und Cl2Pt(NH2CH(CO2H)CH2CH2SR) mit PCl5 werden die Aminosäurechlorid-Komplexe von Platin(IV) 1 und 2 erhalten. Die oxidative Addition der N-geschützten Aminosäurechlorid- Liganden in 1 und 2 an die Platin(0)-Verbindung (C2H4)Pt(PPh3)2 liefert die Chloro-α-aminoacyl-Komplexe 3 und 6.

    Description / Table of Contents: Reactions of Planar Isocyanato-d8-Metal Complexes with SO2, DMSO, and CS2 in the Presence of MethanolThe isocyanato complexes (R3P)2M(NCO)2 (M = Pd, Pt) react with SO2 and methanol to give methoxysulfonyl complexes 1 and 2. (Ph3P)2Pd(NCO)2 affords with SO2 or DMSO in methanol probably polynuclear complexes [(Ph3P)PdL]n 4 an d5 (L == SO2, · DMSO). Reaction with CS2 and methanol yields the dithiocarbonate complexes 7. The adducts of (Ph3 P)2Pd(NCO)2-1r(CO)X(X =N3, NCO) with one (8) and two SO2 ligands (9) as well as (Ph3P)2Pd(NCO)2 · 2SO2 (10) and (Ph3P)2Ir(CO)X · DMSO (11) are described.
    Notes: Die Isocyanato-Komplexe (R3P)2M(NCO)2 (M = Pd,Pt) setzen sich mit SO2 und Methanol zu Methoxysulfonyl-Komplexen 1 und 2 um. (Ph3P)2Pd(NCO)2 liefert mit SO2 oder DMSO in Methanol vermutlich mehrkernige Komplexe [(Ph3P)PdL]n 4 und 5 (L = SO2, DMSO). Mit CS2 in Gegenwart von Methanol entstehen die Dithiocarnbonato- Verbindungen 7. Die Addukte von (Ph3P)2Ir(CO)X (X = N3,NCO) mit einem (8) oder zwei SO2 als Liganden (9) sowie (Ph3P)2Pd(NCO)2 · 2 SO2 (10) und (Ph3P)2Ir(CO)X · DMSO (11) werden beschrieben.
