Rearrangement of allyl 3-thienyl sulfide (45) gives 2-methyl-2,3-dihydrothieno[3,2- >]thiophene (46) [Eq. (21)]. 

Thienyl sulfides with the 2-position of the thiophene ring blocked, e.g., allyl 2-methyl-3-thienyl sulfide (51), also undergo sigmatropic rearrangement when heated in quinoline [Eq. (23)]. 2,6-Dimethyl-2,3-dihydro-thieno[3,4-Z ]thiophene (52) is formed, together with other products. 

Reaction of 2-thienyl propargyl sulfide (98) in HMPA led to 2i/-thieno[2,3-Z ]thiopyran (99) (Equation (21)). Claisen type rearrangements are involved in the reaction, which proceeded in excellent yields. The reaction is also a useful method for the preparation of 57/-thieno[3,2-6]thio-pyran and methyl derivatives of these compounds <69RTC732,72RTC785).
