monosubstituted allyl reagents under Pd-catalyzed asymmetric allylic alkylation reaction conditions to provide products with high regio-, diastereo-, and enantioselectivities. The usefulness of the protocol has been demonstrated by the ready conversion of the allylated products into the corresponding alcohols, esters, and ketones with retention of stereochemistry as well as by the enantioselectivesynthesis of

Palladium catalyzed coupling of acid chlorides and trimethyl(tributylstannyl)silane proves to be a convenient method for the preparation of both aromatic and aliphatic acylsilanes.

The reaction, in the presence of soluble lithium salts, of non-stabilized ylides at low temperature with aliphatic derivatives of acylsilanes gives moderate to good (37–82%) yields of Z-1,2-disubstituted vinylsilanes in excellent (96%) isomeric purities for normal alkyl derivatives. Implications of these results on the mechanistic aspects of the Wittig olefination are discussed

Whereas Li(t-Bu) is an efficient base for the generation of Ph3PCHOMe, Li(n-Bu) gives both this ylide and a butylidene ylide which is consistent with a Ph2(MeOCH2)PCH(n-Pr) formulation. P-31 NMR studies and their reactions with acylsilanes are described.
