= C6H3(Me)(OH)] and, in the second library, amide-functionalised, isomeric ligands Ph2PCH2NCH2C(O)NH(Ar)}CH2PPh2 [2a–e; Ar = C6H3(Me)(OH)], were synthesised by reaction of Ph2PCH2OH and the appropriate amine in CH3OH, and isolated as colourless solids or oils in good yield. The non-methyl, substituted diphosphines Ph2PCH2NCH2C(O)NH(Ar)}CH2PPh2 [2f, Ar = 3-C6H4(OH); 2g, Ar = 4-C6H4(OH)] and Ph2PCH2N(Ar)CH2PPh2
使用单晶 X 射线晶体学广泛研究了两个系列的异构苯酚取代氨基甲基膦作为游离配体并与 Pt II结合的固态行为。在第一个库中,Ph 2 PCH 2 N(Ar)CH 2 PPh 2 [ 1a – e ; 类型的异构二膦;Ar = C 6 H 3 (Me)(OH)] 以及在第二个库中,酰胺功能化的异构配体 Ph 2 PCH 2 NCH 2 C(O)NH(Ar)}CH 2 PPh 2 [ 2a –电子; 氩 = C6 H 3 (Me)(OH)]是通过Ph 2 PCH 2 OH和合适的胺在CH 3 OH中反应合成的,并以良好的收率分离为无色固体或油状物。非甲基取代二膦Ph 2 PCH 2 NCH 2 C(O)NH(Ar)}CH 2 PPh 2 [ 2f , Ar = 3-C 6 H 4 (OH); 2g , Ar = 4-C 6 H 4 (OH)] 和 Ph 2 PCH 2 N(Ar)CH 2 PPh
