Organozinc Coordination Chemistry and Catalytic Effects of Organozinc Coordination Compounds

A review of the present state of organozinc coordination chemistry. with special emphasis on compounds of the type R–Zn–X is given. Their preparation as well as some factors determining their structure and stability are discussed. Certain organozinc coordination compounds have been found to be effective catalysts for cyclo-oligomerization and polymerization reactions. in particular of oxygen-containing monomers (isocyanates, aldehydes. lactones and epoxides). The present views on the mechanisms of these reactions are given.
