Pt(II)-catalyzed hydroarylation reaction of alkynes with pyrroles and furans
摘要:
A Pt(II) catalyst showed a drastic effect on hydroarylation of alkynes with pyrroles and furans compared with Pd(OAc)(2) catalyst. The hydroarylation reactions proceeded smoothly under mild conditions to double-hydroarylation products in good yields. Mono-adducts Were formed only when the second hydroarylation was inhibited by steric hindrance Of Substrates or low reactivity of the mono-adducts. (C) 2009 Elsevier Ltd. All rights reserved.
