Hydrosilylation of ynals with triethylsilane is catalyzed by RhCl(PPh3)(3) and leads to alpha -triethylsilyl enals. Addition of aryl Grignard reagents takes place to give secondary allylic alcohols which are easily converted to 1,3-disubstituted allenes. (C) 2001 Elsevier Science Ltd. All rights reserved.
