preparation of dichlorocarbene adducts of the following olefins is described: cis- and trans-deca-1,5,9-triene deca-1,trans-4,9-triene, octa-1, trans-3,cis-6-triene, octa-1,trans-3,7-triene, and 5-methylhepta-1,trans-3,6-triene. The relative reactivities of the double bonds towards dichlorocarbene were in the order, conjugated vinyl > conjugated internal > cis > trans > vinyl. The effect of base on some of the
The cooligomerization of butadiene and ethylene catalyzed by a NiCl2–AlEt3–phosphine system was investigated. The cooligomerization product was 1,cis-4-hexadiene or/and 1,trans-4,9-decatriene. Bidentate ditertiary phosphines had remarkable effects on the reaction. The effects of ditertiary phosphines are also described.
