of PTA lithium salt with benzaldehyde to give the water-soluble derivative phenyl(1,3,5-triaza-7-phosphatricyclo[3.3.1.13,7]dec-6-yl)methanol (PZA, 1) as a mixture of two diastereoisomers. PZA derivatives phenyl(1,3,5-triaza-7-phospha-tricyclo[3.3.1.13,7]dec-6-yl)methanol sulfide [PZA(S), 2] and oxide [PZA(O), 3] were also synthesized. The latter was isolated in the solid state, and the X-ray crystal
通过PTA锂盐与苯甲醛反应制得非对映体富集的1,3,5-triaza-7-phosphaadamantane(PTA),得到水溶性衍生物苯基(1,3,5-triaza-7-phosphatritricyclo) [3.3.1.13,7] dec-6-基)甲醇(PZA,1)为两种非对映异构体的混合物。PZA衍生物苯基(1,3,5-triaza-7-phospha-tricyclo [3.3.1.13,7] dec-6-yl)甲醇硫化物[PZA(S),2]和氧化物[PZA(O),3]也被合成了。后者以固态分离,并且获得单一非对映异构体的X射线晶体结构。化合物1用作朝向铱(III)部分的k1-P单齿配体,并以溶液和固体形式的非对映异构体混合物形式获得了钢琴凳配合物[Cp * IrCl2(PZA)](4)。 。
