In the presence of HX, carbanions MeseBCHLiRl react with afiphatic aldehydes to give alkenes. The stereochemistry of the product alkene depends upon the nature of HX. In our previous paper1 we showed that in the presence of TFAA or NCS, anions (1) (W&H) yield ketones rather than alkenes when react
The reaction of diphenyl(methoxymethyl)phosphine oxide 1 with organometallic reagents was found to lead to substitution of the methoxymethyl group. The P-phenyl substituent showed a lower propensity to undergo a displacement.
## Abstract A number of oligomeric __p__βphenylenesilanes containing 2β6 silicon atoms per molecule and a series of low molecular weight polyβ__p__βphenylenesilanes (n = 10β30) have been prepared by Wurtzβtype condensation reactions involving appropriate combinations of __p__βchlorophenylβ and chlo
