Acyl iodides in organic synthesis: X. Reactions with triorganylsilanes and triphenylgermane

Reaction of acyl iodides RCOI (R = Me, Ph) with triorganylsilanes R′2R″SiH in toluene gives 50-60% of the corresponding triorganyliodosilanes R′2R″SiI. Triethylsilane reacts with the same acyl iodides under solvent-free conditions to afford the corresponding aldehyde and triethyliodosilane as primary products. Triethyliodosilane undergoes subsequent transformations into hexaethyldisiloxane and triethyl(acyloxy)silane Et3SiOCOR (R = Me, Ph). Reactions of acyl iodides RCOI (R = Me, Ph) with triphenylgermane in the absence of a solvent lead to formation of iodo(triphenyl)germane in more than 90% yield.

Zinc Bis(triphenylsilyl) Stabilized by N-Heterocyclic Carbene

Triphenylsilylzinc compounds stabilized by an N-heterocyclic carbene, [Zn(SiPh3)2(IMes)] (2) and [ZnX(SiPh3)(IMes)] [X = Cl (3a), Br (3b), I (3c)] [IMes = 1,3-Bis(2,4,6-trimethylphenyl)imidazole-2-ylidene], were synthesized by transmetalation from [ZnX2(IMes)(THF)0–1] [X = Cl (1a), Br (1b), I (1c)] and [LiSiPh3(THF)3]. According to single-crystal X-ray diffraction, [Zn(SiPh3)2(IMes)] (2) shows a trigonal-planar coordinated central zinc atom, whereas [ZnCl(SiPh3)(IMes)(THF)] (3a-THF) shows a distorted tetrahedral coordination.

Acyl iodides in organic synthesis. Reaction of acyl iodides with triphenylethoxy- and triphenylhydroxysilane

The reaction of triphenylethoxysilane with acetyl or benzoyl iodide led to the formation of triphenyliodosilane and ethyl ester of the corresponding carboxylic acid. Triphenyliodosilane formed also in the reaction of triphenylsilanol with benzoyl iodide.

Selective synthesis of halosilanes from hydrosilanes and utilization for organic synthesis

Selective synthesis of halosilanes has been examined. Various types of halosilanes and halohydrosilanes, such as R3SiX, R2SiHX, R2SiX2, RSiH2X, RSiHX2 (X=Cl, Br, F), were obtained by the reactions of the corresponding hydrosilanes with Cu(II)-based reagents selectively in high yields. This method could be also applied to the synthesis of chlorofluorosilanes and chlorohydrogermanes. On the other hand, iodo- and bromosilanes and germanes were obtained by Pd- or Ni-catalyzed hydride-halogen exchange reactions of hydrosilanes with alkyl or allyl halides. Their synthetic applications have been demonstrated by using iodo- and bromosilanes and chlorofluorosilanes.
