Water-soluble and reusable copper catalyst for the allylic benzoyloxylation of olefins
摘要:
Simple mixing of [(HOCH(2)CH(2)NHCOCH(2))(2)NCH(2)](2) with Cu(MeCN)(4)BF(4) in water led to an efficient and reusable catalytic system for the allylic oxidation of olefins by tert-butyl perbenzoate. (C) 2002 Elsevier Science Ltd. All rights reserved.

Allylicsubstitution of PhCH(OAc)CHCHPh by CH2(COMe)2 in a basic MeOH/H2O mixture could be achieved in the absence of a palladiumcatalyst and lead to a mixture of PhCH(CH(COMe)2)CHCHPh and PhCH(OMe)CHCHPh in 40% and 55% yields, respectively. The process is induced by water, and nucleophilic attack addition occurred on a stabilized carbocation as the intermediate. Addition of a catalytic amount of
