Procedure

A solution of 1-dodecyne (50.0 g), tributyltinhydride (109.4 g), and azobisisobutyronitrile (100 mg) was stirred at 95° C. for 3 hrs. The reaction mixture was cooled to 50° C. and evaporated. The residue was filtered through a column of silica, using hexane as the eluent. The appropriate fractions were collected and evaporated. The residue was dried under vacuum to give 131.7 g (96.0%) of tri-n-butyl-1-dodecenylstannane.
