7-diene 1-sulfides have been prepared by the reaction of α,β unsaturated ketones with P4S10 in the presence of NEt3. 1,2-Thiaphosphole 2-sulfides generated by the thermolysis of the phosphabicyclo compounds underwent cycloaddition reactions with acrylonitrile, styrene, butyl vinyl ether and norbornene to give the [4+2]cycloadducts, respectively.
2,9-Dithia-1-phosphabicyclo[4.3.0]nona-3,7-diene 1-sulfides 已通过 α,β 不饱和酮与 P4S10 在 NEt3 存在下的反应制备。由磷双环化合物热解产生的 1,2-硫磷杂 2-硫化物与丙烯腈、苯乙烯、丁基乙烯基醚和降冰片烯进行环加成反应,分别得到 [4+2] 环加合物。
