methanol–benzene on the selectivity and the rate of metalloene reactions of different allyltin compounds with singlet oxygen, 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD) and diethyl azodicarboxylate (DEAD) was studied. Analogous comparative studies were carried out in Et2O and 4 mol dm−3 solutions of LiClO4 in diethyl ether. In the reaction with PTAD and 1O2 the more polar solvent favoured the production
溶剂二元混合物甲醇-苯的极性增加对不同烯丙基锡化合物与单线态氧,4-苯基-1,2,4-三唑啉-3,5-二酮的选择性和金属茂反应速率的影响( PTAD)和偶氮二羧酸二乙酯(DEAD)进行了研究。在LiClO 4在乙醚中的Et 2 O和4 mol dm -3溶液中进行了类似的比较研究。在与PTAD和1 O 2的反应中,极性更大的溶剂有利于M-烯产物的产生,而环加成反应则由非极性溶剂有利。
