New tricyclic hexacoordinated phosphoranes 1−6 with internal N→P coordination containing ring sizes varying from five to eight membered have been synthesized by oxidative addition of a quinone or a diol to a cyclic phosphite. The bicyclic phosphorane (NC9H6O)P(O2(3,5-t-Bu)2C6H2)((O-2,4-(t-Bu)2C6H2)2CH2)·1/2H2O (7·1/2H2O) has been synthesized by adding the 3,5-di-tert-butyl-o-benzoquinone to the cyclic
通过将醌或二醇氧化加成到环状亚磷酸酯,合成了具有内部 N→P 配位的新三环六配位正膦 1-6,其环大小从 5 元到 8 元不等。双环正膦 (NC9H6O)P(O2(3,5-t-Bu)2C6H2)((O-2,4-(t-Bu)2C6H2)2CH2)·1/2H2O (7·1/2H2O)通过将 3,5-二-叔丁基-邻苯醌添加到环状亚磷酸酯中合成。化合物 (NC9H6O)P(2,2'-OC6H4C6H4O)2 (6) 由磷烷通过磷磷脂以两种方式进行的新型环交换反应产生:(a) 通过用 2 ,2'-联苯酚/N-氯二异丙胺和 (b) 通过用 8-羟基喹啉处理 (Et2N)P(OCH2CMe2CH2O)(2,2'-OC6H4C6H4O)。用 8-羟基喹啉处理氨基正膦 (Et2N)P(OCH2CMe2CH2O)(O2C14H8) 2,4, 6-三甲基苯甲酸产生独特的酯 (OCH2CMe2CH2O)P(O)OC14H8O(C(O)-2
