Bisamino(diphosphonite), p-C6H4NP(OC6H4C3H5-o)2}2}2 (1), was prepared by reacting p-C6H4N(PCl2)2}2 with four equivalents of o-allylphenol in 85% yield. Compound 1 on treatment with [M(CO)4(HNC5H10)2] (M = Mo or W) gave cis-[M(CO)4}2p-C6H4N(P(OC6H4C3H5-o)2)2}2}] (2, M = Mo; 3, M = W). The reaction of 1 with [Fe(η5-C5H5)(CO)2]2 yielded the complex [Fe(η5-C5H5)(μ-CO)}2p-C6H4N(P(OC6H4C3H5-o)2)2}2}] (4)
通过使p -C 6 H 4 N(PCl )反应,制得双氨基(二膦酸酯)p -C 6 H 4 N P(OC 6 H 4 C 3 H 5 - o)2 } 2 } 2(1)。2)2 } 2具有四当量的邻烯丙基苯酚,产率为85%。用[M(CO)4(HNC 5 H 10)2 ](M = Mo或W)处理的化合物1得到顺式-[M(CO)4 } 2 p -C 6 H 4 N(P(OC 6 H 4 C 3 H 5 - o)2)2 } 2 }]}(2,M = Mo; 3, M = W)。的反应1用的[Fe(η 5 -C 5 H ^ 5)(CO)2 ] 2,得到络合物[的Fe(η 5 -C 5 H ^ 5)(μ-CO)} 2 p -C6 H 4 N(P(OC 6 H 4 C 3 H 5 - o) 2) 2 } 2 }]( 4)。用Fe(CO) 5处理1提供了单核络合物[Fe(CO) 3 }
