摘要：
Reactions of trans-Pd(SiF2Ph)(2)L-2 (L = PMe3 (1a), PMe2Ph (1b), PMePh2 (1c)) with allyl bromide readily proceeded in CH2Cl2 at -20 degrees C to form CH2=CHCH2SiF2Ph and the corresponding bromo(silyl)palladium complexes, trans-PdBr(SiF2Ph)L-2 (2a-2c) in high selectivities. Treatment of 1a-1c with dry HCl in CH2Cl2 at -20 degrees C gave silyl chloride complexes, trans-PdCl(SiF2Ph)L-2 (3a-3c), respectively. Complexes 2a-2c and 3a-3c were isolated and characterized by NMR spectroscopy and/or elemental analysis. One of the complexes, trans-PdCl(SiF2Ph)(PMe2Ph)(2) (3b), was identified also by X-ray diffraction study. Relevance of bis-silyl complexes to catalytic silylation of allylic compounds with disilanes is discussed. (C) 1999 Elsevier Science S.A. All rights reserved.
