A new rhodium trinuclear complex containing highly protected hydroxo groups, [{Rh(binap)}3(µ3-OH)2]CIO4, responsible for deactivation of the 1,3-hydrogen migration catalyst of allylamine [binap = 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl]

Abstract

A new stable rhodium trinuclear complex, [{Rh(binap)}₃(µ₃-OH)₂]ClO₄[binap = 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl](2), formed when water deactivates the Rh^I–binap complex catalysed asymmetric 1,3-hydrogen migration of allylamine, has been isolated; and X-ray structural analysis of the deuterium derivative [{Rh[(+) binap]}₃(µ₃-OD)₂]ClO₄ revealed a unique structure with two highly protected µ₃-hydroxo groups.
