TRANS-VINYLSILANES VIA SUZUKI-MIYAURA COUPLING
Soderquist, John A.,Colberg, Juan C.
, p. 27 - 28 (1994)
Representative aryl, vinyl and alkynyl bromides undergo efficient Pd-catalyzed cross coupling with trans-1-(9-borabicyclonon-9-yl)-2-(trimethylsilyl)ethene (1) under basic conditions to produce the corresponding trans styryl-, dienyl- and enynylsilanes (58-89percent).
A New Elimination-Rearrangement Involving Silicon Migration
Menichetti, Stefano,Griffiths, Gwerydd,Stirling, Charles J. M.
, p. 54 - 55 (1992)
Lithium diisopropylamide (LDA), a strongly basic, poorly silicophilic nucleophile reacts with α-phenylsilanes bearing β-leaving groups to cause 1,2-silyl migration and loss of the leaving group.

A palladium complex coordinated with a chiral SIPHOS ligand was evaluated as an efficient catalyst for asymmetric hydrosilylation of β-silyl styrenes with trichlorosilane and 23 1,2-bis(silyl) chiral compounds were produced. Good to excellent enantioselec

Chromium complexes have found very little applications as hydrogenation catalysts. Here, we report a Cr-catalyzed semi-hydrogenation of internal alkynes to the corresponding Z-alkenes with good stereocontrol (up to 99/1 for dialkyl alkynes). The catalyst comprises the commercial reagents chromium(III) acetylacetonate, Cr(acac)3, and diisobutylaluminium hydride, DIBAL?H, in THF. The semi-hydrogenation operates at mild conditions (1-5 bar H2, 30 °C).
