Title:
DIMERIZATION OF OLEFIN
Document Type and Number:
Japanese Patent JP2686427
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an optically active vinylcycloheptane from bicycloheptane and ethylene in a high time and space yield, by using both a π-allylnickel halide/ azaphospholene complex and a Lewis acid.
SOLUTION: A π-allylnickel halide/azaphospholene complex is prepared by using an azaphospholene of the formula (R1 and R2 are each an alkyl, an aryl or an aralkyl). A Lewis acid such as an organoaluminum or organoboron halide or the like is added to the complex and is reacted with a mixture of ethylene and bicycloheptane or a mixture of ethylene and styrene to give an optically active vinylbicycloheptane or an optically active 3-phenylbutene-1. For example, a compound of the formula RAlX3, R3Al2X4 or R2AlX4 (R is an alkyl or an aryl; X is Cl, Br or I) such as EtAlCl3, Et3Al2Cl4, Et2AlCl2 or the like or BF4 is used as a complex anion.
