Kudo, Hiroto published the artcileLiving Ring-Expansion Polymerization of Thiirane with Cyclic Monocarbamothioates, Application In Synthesis of 151-10-0, the main research area is living ring expansion polymerization thiirane cyclic monocarbamothioate.
We synthesized two kinds of monocarbamothioates TZO(R) containing a thiazolidin-2-one (TZO) skeleton and TZD(R) containing a thiazolidine-2,4-dione (TZD) skeleton. In the reaction of TZO(R) and phenoxypropyrenesulfide (PPS) using tetrabutylammonium chloride (TBAC) as a catalyst in 1-methyl-2-pyrrolidinone at 60°C, anionic ring-opening polymerization of PPS proceeded to give the corresponding linear polysulfides, polyPPS, with Mn = 75 860-206 700 (Mw/Mn = 1.54-1.73) in high yield. In contrast, in the reaction of TZD(R) and PPS, the continuous insertion reaction of PPS into TZD(R), i.e., living ring-expansion polymerization, occurred to afford cyclic polysulfides TZD(R)-c-poly(PPS)n with Mn = 1870-33 420 (Mw/Mn = 1.07-1.26) in high yield. The ring size could be controlled by the feed ratio of TZD(R)/PPS in the range of 1/5-1/100.
Macromolecules (Washington, DC, United States) published new progress about Anionic ring-opening polymerization. 151-10-0 belongs to class isoquinoline, name is 1,3-Dimethoxybenzene, and the molecular formula is C8H10O2, Application In Synthesis of 151-10-0.
