Im. Baibich et al., A COMPARATIVE-STUDY OF HYDROSILANE COMPOUNDS AS COCATALYSTS IN THE METATHESIS OF 1-HEXENE, Journal of molecular catalysis. A, Chemical, 136(3), 1998, pp. 213-217
The selectivity of I-hexene metathesis using WCI6 as catalyst was eval
uated with a series of hydrosilane-compounds as cocatalysts: Ph3SiH, P
h2SiH2, PhSiH3 and polymethylhydrosiloxane (PMHS). The metathesis reac
tion is favored by the addition of promoters. When in the presence of
WCl4(OAr)(2), OAr = 2,6-dichlorophenoxide, 2,6-difluorophenoxide, olef
in metathesis occurs with good selectivity without the use of promoter
