반응 단계

To diphenylphosphine (18.6 g, 1.0 mol) heated to 140° C. under nitrogen, a mixture of vinyl triethoxysilane (19.0 g, 1.0 mol) and di-t-butyl peroxide (1.92 g) is added with stirring during 3/4 hour. The solution is held at 140°-160° C for an additional hour. Distillation in vacuum gives the product (24.7 g, 65.7 percent yield, b.p. 162° C/0.3 mm, nD27 1.5370. The efficiency on the basis of the vinyl silane consumed is 93 percent. The H'NMR, delta (C6H6): 0.8 (m, 2H). 1.12 (t, 9H); 2.24 (m, 2H); 3.76 (q, 6H); and 7.0-7.7 (m, 10H) is consistent with the expected structure.
