Treatment of the compounds [M(CO)5(NCMe)] (M=Cr, Mo, W) with the phenylazonaphthylphosphines 4-R–PhN2-1-C10H5-2-OR′-6-PPh2 R′=H, R=H (I), R=Me (II), R=Et (III), R=Pri (IV) R=But (V); R′=C(O)Me, R=Me (VI)} afforded the mono-substituted products [M(CO)5(L)] (1-8) (M=Cr, L=II, 1; M=Mo, L=I–VI, 2–7; M=W, L=II, 8). Further reaction of cis-[Mo(CO)4(piperidine)2] with the azo-phosphines I–V afforded the
用苯基氮杂萘膦4-R–PhN 2 -1-C 10 H 5 -2-OR'-6-PPh 2处理化合物[M(CO)5(NCMe)](M = Cr,Mo,W) R'= H,R = H(我),R =我(II),R =逸(III)中,R = PR我(IV)R =卜吨(V); R'= C(O)Me,R =我(VI)},得到单取代产物[M(CO)5(L)](1 - 8)(M =铬,L = II,1 ; M = Mo,L = I – VI,2 –7;M = W,L =II,8)。的进一步反应的顺式- [沫(CO)4(哌啶)2 ]与偶氮膦我- V,得到二取代的复合物的顺式- [沫(CO)4(L)2 ](9 - 13); 而与VI反应可得到顺式-[Mo(CO)4(II)2 ] 10,而不是预期的化合物顺式-[Mo(CO)4(VI)2](14)。然而,可以通过将10酯化来制备14。进一步研究了观察到的哌啶对顺式[[Mo(CO)4(哌啶)2
