Ie. Mikhailov et al., CIRCUMAMBULATORY REARRANGEMENTS OF DITHIOACYLOXY GROUPS AROUND THE CYCLOPENTADIENE RING, Mendeleev communications, (4), 1994, pp. 120-122
Circumambulatory rearrangements of dithioacyloxy groups around the cyc
lopentadiene ring have been found to occur by a 3,3-sigmatropic shift
(hetero-Cope) mechanism with energy barriers in the range of 24-30 kca
