• (3,3)Sigmatropic Ring Expansion of Cyclic Thionocarbonates. IV. Relationship between Ring Size of Cyclic Thionocarbonates and Geometry of Created Double Bond in Medium- and Large-Membered Thiolcarbonates.

  Medium- and large-membered cyclic thiolcarbonates containing an (E)- or (Z)-double bond were synthesized by two methods using [3, 3]sigmatropic ring expansion of cyclic thionocarbonates. The [3, 3]sigmatropic ring expansion proceeds exclusively via the transition state bearing the chain tethered in a cis relationship when the cyclic thionocarbonates are 8-membered or smaller. Importantly, the ring size of the cyclic thionocarbonate determines the double bond geometry of the thiolcarbonate.Conversion of the cyclic thiolcarbonates into (E)- or (Z)-allylic sulfides is also described.

  通过两种方法，利用环状硫羰酸酯的[3,3]σ迁移环扩张反应，合成了含有（E）或（Z）双键的中大型环状硫醇碳酸酯。当环状硫羰酸酯为8元或更小时，[3,3]σ迁移环扩张反应仅通过过渡态进行，该过渡态中的链以顺式关系系留。重要的是，环状硫羰酸酯的环大小决定了硫醇碳酸酯的双键几何形状。本文还描述了将环状硫醇碳酸酯转化为（E）或（Z）型烯丙基硫醚的方法。

Other solvents may be present. Some of the said principal solvents are novel compounds and/or novel mixtures. Premixes of the fabric softening actives, the principal solvents, and, optionally, other solvents are useful in the preparation of complete formulations by obviating/limiting the need for heating.
