Higher order mixed organocuprate

B.H. Lipshutz, Application of Higher-Order Mixed Organocuprates to Organic Synthesis, Synthesis 1987, 325, s.d.S.335ff. [Pg.1333]

In contrast to their reaction with R R CuLi (R = alkyl, R = alkyl or CN), the reactions of epoxides with the higher order mixed organocuprates R2Cu(CN)Li2 (R = various alkyl or aryl) give excellent yields of ring-opened products. The trisubstituted oxiran (190), on reaction with Pr"Cu(CN)Li, affords only 23% of (191), but with Pr"2Cu(CN)Li2 the yield is increased to 86%. [Pg.32]
