Using the sacrificial anode technique, the electroreduction of arylchlorosilanes into the corresponding arylhydrosilanes occurs via a silylaluminium intermediate characterized for the first time in such reactions.
Twenty-one organosilyl- and organogermyl- substitutedferrocenes, most of which contain the M—M(M = Si or Ge) groupings, have been prepared and their 1H NMR spectra have been recorded. The preparations of some organic derivatives of silicon and germanium used in the synthesis are also described.

SiX3-SiXiMe3−i (i = 0, 1, 2; X = Cl, Br), trisilanes SiX2(SiXiMe3−i) (i = 0, 1) and branched tetrasilanes SiX(SiXMe2)3 were synthesized and their behavior towards the Lewis-base catalyzed hydrogenation by stannanes was investigated. In the case of methylchlorodisilanes SiCl3-SiCliMe3−i Si-Si bond cleavage competes with the hydrogenation reaction.

An Unusual and Diastereoselective Rearrangement during an Intramolecular Ene Reaction Involving a Disilane
A chiral 1-isopropenyl-1-(3-oxopropyl)disilane derivative undergoes a type II ene reaction under Lewis acid catalyzed conditions to afford the silacyclic compound and an unexpected rearranged product with high diastereoselectivities. This rearrangement occurs through 1,2-migration of a trimethylsilyl group. A common intermediate was proposed to explain the formation of both products.

The photolysis of aryl-substituted disilanes in the presence of dimethyl sulfoxide has been studied. The products are found to be disiloxanes, aryl-substituted silanes, dimethylsilanone [(CH3)2Si=O], and dimethyl sulfide. Possible mechanisms for these reactions are discussed.
