Abstract A new anionic ring-opening polymerization (ROP) was used to synthesize polydithiocarbonates from cyclic dithiocarbonates. The polymerization was optimized in the presence of dibenzo-18-C-6 and NaH/EtOH, and carried out at 50 °C to suppress any retropolymerization. Six- and seven-membered cyclic dithiocarbonates underwent ROP to afford the corresponding polymers. Thermal depolymerization of
摘要用一种新型的阴离子开环聚合法(ROP)从环状二硫代碳酸酯合成聚二硫代碳酸酯。在二苯并-18-C-6和NaH / EtOH的存在下优化聚合反应,并在50°C进行以抑制任何逆聚合。对六元和七元环状二硫代碳酸酯进行ROP,得到相应的聚合物。制备的聚合物的热解聚反应生成二聚体,根据1H核磁共振(NMR)光谱,发现该二聚体是一种反咬合机理。线型聚合物的特征结构通过1 H NMR和13 C NMR光谱法确定,并与单体进行比较。80°C下的ROP表现出被二聚体污染的聚合物的形成。

Reaction of manganic acetate with diphenyidisulplilde in dichloromethane-trifluoroacetic acid in the presence of allylic esters or amides of allylamine gives trifluoroacetoxysulphides and hence by ready hydrolysis vicinal hydroxysulphides. The regiochemical outcome can be controlled by selection of either an acetyl- or trifluoroacetyl derivative.
