Rhodium-mediated silylative cyclization of 1,6-heptadiynes
摘要:
RhCl(PPh3)(3) readily reacts with an equivalent mole of a hydrosilane to form the Si-Rh-H species that plays an important role in the silylative cyclization of 1,6-heptadiynes to construct 1,2-dialkylidenecyclopentane derivatives. (C) 1998 Elsevier Science Ltd. All rights reserved.
