## Stereoselective Preparation and Reaction of Chiral Secondary Cycloalkyl-and Alkyl-Zinc Reagents. -A new procedure for the synthesis of configurationally stable chiral organozinc reagents such as (III) and (VII) is described which uses enantioselective hydroboration with (-)-isopinocampheylbora
Preparation of Silyl-Substituted Dizinciomethanes and Their Reactions with Electrophiles. -Silylated dibromomethanes (I) react with finely divided zinc in the presence of catalytic amounts of PbCl 2 to give the corresponding dizincio compounds (II). These can be subjected to stepwise reactions with
