Thermolysis of the cyclic α-vinyl sulfonium p-toluenesulfonylimides (6a-c), prepared from 2-vinylthiolane (5a), 2-vinylthiane (5b), and 2-vinylthiepane (5c) by treatment with chloramine T, resulted in -sigmatropic rearrangement with ring-expansion to
THERMAL RING EXPANSION OF 2-VINYLTHIACYCLOALKANE N-IMIDES BY -SIGMATROPIC REARRANGEMENT
Sashida, Haruki,Tsuchiya, Takashi
, p. 1303 - 1306 (2007/10/02)
The thermolysis of the 2-vinylthiacyclo-pentene, -hexane, and -heptane N-(p-toluenesulfonyl)imides (7) resulted in the -sigmatropic rearrangement to give the corresponding ring expansion products (8).
