    Notes: Abstract The paramural bodies of Albugo candida were formed solely by elaboration of the plasmalemma. Two major forms were recognized: one consisting of plasmalemmal invaginations projecting into the cytoplasm; the other appearing like a pocket containing a number of vesicles and tubules. It is suggested that the first is the basic form of paramural body. In sporangia the paramural bodies break away from the plasmalemma and undergo autodigestion while in vegetative hyphae their tubules and lamellae break up into vesicles that are finally sequestered into the wall.

    Notes: Transition Metal Silyl Complexes, 44.  -  Preparation of the Binuclear Silyl Complexes (CO)3(R3Si)Fe(μ-PR′R′′)Pt(PPh3)2 by Oxidative Addition of (CO)3(R′R′′HP)Fe(H)SiR3 to (C2H4)Pt(PPh3)2The complexes (CO)3(R′R′′HP)Fe(H)SiR3 (1) [PHR′R′′ = PHPh2, PH2Ph, PH2Cy; SiR3 = SiPh3, SiPh2Me, SiPhMe2, Si(OMe)3] react with Pt(C2H4)(PPh3)2 to give the dinuclear, silyl-substituted complexes (CO)3(R3Si)Fe(μ-PR′R′′)Pt(PPh3)2 (2) in high yields. Upon reaction of 2 (R = R′ R′′ = Ph) with CO, the PPh3 ligand at Pt being trans to the PPh2 bridge is exchanged, and (CO)3(Ph3Si)Fe(μ-PPh2)Pt(PPh3)CO (3) is formed. Complex 3 is characterized by an X-ray structure analysis. The rather short Fe  -  Si distance [233.9(2) pm] and the infrared spectrum of 3 indicate that the Fe  -  Pt bond is quite polar.

    Notes: Transition Metal Silyl Complexes, 48[1]. - Synthesis of the New Heterobimetallic Dinuclear Silyl Complexes (OC)3(R3Si)-Fe(μ-PR′R″)Pt(1,5-COD)(Fe-Pt), Phosphane Exchange Reactions of (OC)3(R3Si)Fe(μ-PR′R″)Pt(PPh3)2(Fe-Pt), and Preparation of the Dihydrido complexes [(OC)3Fe(μ-PPh2)(μ-H)2Pt(PR3)2][BF4](Fe-Pt)The dinuclear, silyl-substituted complexes (OC)3(R3Si)Fe(μ-PR′r″)Pt(1,5-COD) (1) [μ-PR′R″ = PPh2, PCY2, PHPh; SiR3 = SiPh3, Si(OMe)3] were prepared in high yields by the oxidative addition of the hydrido complexes (OC)3(PHR′R″)Fe(H)-SiR3 to Pt(1,5-COD)2. Upon reaction of (OC)3(R3Si)Fe(μ-PR′R″)Pt(PPh3)2 [μ-PR′R″ = PPh2, PHCy; SiR3 = SiPh3, SiPh2Me, SiPhMeCl, Si(OMe)3] with two equivalents of PR‴3 (PMe3, PBu3, PEt3) or with one equivalent of chelating di-phosphanes (vdpp, dppe, dppm) both PPh3 ligands are displaced, and (OC)3(R3Si)Fe(μ-PR′R″)Pt(PR‴3)2 or (OC)3(R3Si)-Fe(μ-PR′R″)Pt[(PPh2)2X] (X = C=CH2, C2H4, CH2) are formed, respectively. When one equivalent of PMe3 is used, only the PPh3 ligand trans to the μ-PPh2 bridge is substituted, and (OC)3(Ph3Si)Fe(μ-PPh2)Pt(PPh3)(PMe3 is formed. The 1,5-COD ligand in 1 is displaced by P(OR)3 to give (OC)3-(Ph3Si)Fe(μ-PPh2)Pt[P(OR)3]2 (R = Me, Ph). The complexes (OC)3(Ph3Si)Fe(μ-PPh2)Pt(PMe3)2and (OC)3(Ph3Si)Fe(μ-PPh2)Pt[(PPh2)2C=CH2] were characterized by X-ray structure analysis. The short Fe-Si distances [233.0(2) and 235.6(3) pm] and the infrared v(CO) absorptions indicate that the Fe-Pt bonds are quite polar. Protonation of (OC)3(Me2-PhSi)Fe(μPPh2)Pt(PPh3)2 with CF3COOH gives the hydrido-bridged complex [(OC)3(Me2PhSi)Fe(μ-PPh2)(μ-H)Pt-(PPh3)2][O2CCF3]. Upon addition of an excess of HBF4 · Et2O to (OC)3(R3Si)Fe(μ-PPh2)Pt(PPh3)2 (R = Ph, OMe), (OC)3-Si)Fe(μ-PPh2)Pt[Pt[P(OMe)3]2 or (OC)3(Ph2MeSi)Fe(μ-PPh2)-Pt(dppe) R3SiF is split, and the corresponding μ-dihydrido complexes [(OC)3Fe(μ-PPh2)(μ-H)2Pt(PR3)2][BF4] are obtained.
