摘要：

Triaryl phosphites selectively reduce aryl selenoxides to selenides. The Hammett plot of the reactions of para-phenyl substituted triaryl phosphites with diphenyl selenoxide gave rho = +2.3, whereas with bis(p-methoxyphenyl) selenoxide. rho = -2.1. The results are consistent with a concerted mechanism for the oxygen transfer from Se to P. (C) 2002 Elsevier Science Ltd. All rights reserved.
