Intramolecular allyl, benzyl or methylene ester transfer is observed upon treatment of suitably functionalized 1,3-thiazanes with catalytic amounts of either anhydrous iridium trichloride or chlorotricarbonyliridium in benzene under a carbon monoxide atmosphere (e.g. N-allyl-2-phenyl-1,3-thiazane is converted to N,S-diallyl-N-benzyl-1,3-aminothiol; the allyl unit is provided by a second molecule of the thiazane, which is in turn converted into the corresponding thiazine by formal loss of propene).
在一氧化碳气氛下,用催化量的无水三氯化铱或氯代三羰基铱在苯中处理适当官能化的 1,3-噻氮烷(例如 N-烯丙基-2-苯基-1,3),观察到分子内烯丙基、苄基或亚甲基酯转移。 -噻嗪转化为N,S-二烯丙基-N-苄基-1,3-氨基硫醇;由噻嗪的第二个分子提供,该分子又通过丙烯的形式损失而转化为相应的噻嗪)。
