Reaction Conditions

Reaction Steps

A 100 ml 3-necked round bottomed flash was heated to 100° C. under a nitrogen atmosohere and 7.14 g diohenylphosphine (38.4 mmole), 0.15 g 2,2'-azobis (2-methyloropionitrile), and 3.77 g N-vinyl-N-methyl acetamide (38.1 mmole) from Polysciences were added in the stated sequence. The reaction was maintained at 100° C. for 45 minutes under a nitrogen atmosphere and then evacuated (1 mm) for 24 hours at 100° C. A viscuous oil resulted whose infrared spectrum disolayed a strong γ(CO) band at 1645 cm-1 and a small γ(P--H) band at 2300 cm-1 due to a small amount of diphenylphosphine impurity. The elemental analysis was the following: calculated (found); C, 71.58 (69.89); H, 7.02 (7.15); N, 4.91 (4.57); P, 10.87 (10.97). The yield was 94%.
