interesting new transformations of thiirane, 2(R),3(S)-dimethylthiirane (cis-DMT), and 2(R),3(R)(2(S), 3(S))-dimethylthiirane (trans-DMT) by the W(CO)sub 5} group. The reaction of an excess of thiirane with W(CO)sub 5}-(NCMe) leads to the formation of the cyclic polydisulfides (CHsub 2}-CHsub 2}SS)sub n}, 1-4, n = 2-5 plus ethylene catalytically. The case of this new catalytic thiirane reaction indicates
本文报道了硫杂丙烷、2(R),3(S)-二甲基硫杂丙烷 (cis-DMT) 和 2(R),3(R)(2(S), 3(S))-二甲基硫杂丙烷的一些有趣的新转化(trans-DMT) 由 W(CO)sub 5} 组。过量的硫杂丙环与 W(CO)sub 5}-(NCMe) 的反应导致形成环状聚二硫化物 (CHsub 2}-CHsub 2}SS)sub n}, 1-4 , n = 2-5 加上乙烯催化。这种新的催化硫杂丙环反应的案例表明,它可能是合成大量这些和其他环状聚二硫化物的实用途径。17 参考,1 图。
