In contrast to the behaviour of the entitled disulfide (1) toward Wittig reagents (2a, b), which undergoes direct and simple nucleophilic displacement reactions giving 7a, b, 8 and 9 as the final products, an extensive decomposition occurred when the same disulfide was treated with ylides 2c, d, furnishing the adducts 7c, d, 8 and 12 or 14, respectively. The given structures were based upon analytical
