Reaction Steps

U.S. Pat. No. 3,715,385, Wolgemuth, et al. (1973) describes still another method of obtaining N-vinyl carbamic acid esters by condensation-re-arrangement of acrylonitrile carbonate with methanol or ethanol. In Example I, methyl (N-vinyl carbamate) was obtained in 40% yield from carboethoxy acrylohydroxamate at 100° C. using a sodium alkoxy tin catalyst. The carboethoxy acrylohydroxamate is said to decompose at reaction temperature to yield acrylonitrile carbonate.
