unknown among organophosphates and phosphonic acids. The methyl ester of 2, [(RO)P(O)(OMe)2] (R = 4-Br-2,6-iPr2C6H3) (4), was reacted with a series of boronic acids under Suzuki coupling conditions to yield the corresponding C–C bond coupled products, 3,5-diisopropylbiphenyl-4-yl dimethyl phosphate (5), 4′-formyl-3,5-diisopropyl-biphenyl-4-yl dimethyl phosphate (6) and 4′-(diphenylmethyleneamino)-3,3′,5
新的4-卤代官能化2,6-二异丙基苯基磷酸酯,X-dippH 2 [(RO)P(O)(OH)2 ](R = 4-X-2,6- i Pr 2 C 6 H 3 ; X从相应的4-卤代酚开始,分两个步骤合成了Cl 1,Br 2,I 3),并通过分析,光谱和单晶X射线衍射研究对其进行了表征。同构有机磷酸酯1-3通过相邻的–PO 3 H 2之间广泛的氢键相互作用形成固态的管状结构基团,在有机磷酸酯和膦酸中以前未知的聚集。的甲基酯2,[(RO)P(O)(OME)2 ](R = 4-溴-2,6-我镨2 ç 6 ħ 3)(4),用一系列硼酸反应在Suzuki偶联条件下产生相应的C–C键偶联产物:3,5-二异丙基联苯-4-基磷酸二甲酯(5),4'-甲酰基-3,5-二异丙基联苯-4-基磷酸二甲酯(6)和4'-(二苯基亚甲基氨基)-3,3',5,5'-四异丙基-联苯-4-基二甲基磷酸二甲酯(7)。已经建立了用于
