Abstract Bis (iodozincio) methane, prepared from diiodomethane and zinc, reacts with an organic halide in the presence of a transition-metal catalyst to give an iodozinciomethylenated compound; this then reacts with another organic halide to form a C [BOND] C bond. The overall process connects two electrophiles with one carbon atom. Bis (iodozincio) ethane can also undergo this transformation, yielding a new stereogenic ...
