CATALYST AND METHOD FOR DOUBLE DECOMPOSITION OF OLEFIN

摘要

Compounds of the formula: M(NR1)(OR2)2(CHR3) wherein M is molybdenum or tungsten; R1 and R2 are alkyl, aryl, aralkyl or halogen-substituted derivatives or silicon-containing analogs thereof; R3 is an alkyl, aryl, aralkyl or any substituent that results from the initial reaction between the M=CHR3 complex and the olefin(s) that is(are) being metathesized; alkyl has 1-20 carbons, aryl has 6-20 carbons and aralkyl h as 7-20 carbons. These compounds are catalysts for the metathesis of ordinary olefins (hydrocarbons) and especially functionalized olefins in the homogeneous phase.
