Patent number: 4704377Abstract: Described are novel bimetallic complexes particularly useful as homogeneous catalysts for the metathesis of alkynes and metathesizable functionally substituted alkynes, and methods for the preparation of such complexes. The complexes are formed from (i) a Group VI-B metal compound having (a) quadruple metal to metal bonds between a pair of Group VI-B metal atoms at least one of which has an atomic number above 24, and (b) four monovalent anions with a k.sub.A greater than 10.sup.-14, and (ii) a Group III-A phenoxide, a Group III-A alkoxide or a Group IV-B metal alkoxide. Displacement of two of the anions appears to occur during formation of the complex. Usually the complexes can be produced very easily and quickly. All that is required is to establish intimate contact between components (i) and (ii), preferably in an innocuous liquid organic solvent. Addition of a small amount of a nitrile gives a faster and cleaner reaction. In some cases use of slightly elevated temperatures is desirable.Type: GrantFiled: May 19, 1986Date of Patent: November 3, 1987Assignee: Ethyl CorporationInventor: Steven P. Diefenbach
