Homologation zincates

Generation of homologated organozincs via 1,2-migration of zincate carbenoids... [Pg.102]

The in situ IR observations shown in Figure 20.5 provided the key result that led us to propose that an activator was needed to drive the homologation of zincate enolate 11a, and that the activator in this case was a second equivalent of 7. Our observations appeared similar to those described by Harada and Oku. They had observed certain a-halo diorganozinc compounds could be driven to undergo 1,2-migration if an excess of alkoxide was added (Scheme 20.6). Because higher conver-... [Pg.324]
