Participants

Reaction Steps

The 6-bromomethyl-1,1,4,4-tetramethyl-1,2,3,4-tetrahydronaphthalene (9.0 g, 32.0 mmol) prepared in the previous step is mixed with triphenylphosphine (10.1 g, 38.4 mmol) in solution in 50 ml of dichloromethane for 24 hours, and then diluted with ethyl ether (200 ml). The (5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl)methyl-triphenyl-phosphonium bromide precipitates, is filtered and washed with ether. The white crystals obtained (15.0 g, yield 86%) are dried in a desiccator.
