Stabilization of 7-phosphanorbornadienes by complexation; X-ray crystal structure of 2,3-bis(methoxycarbonyl)-5,6-dimethyl-7-phenyl-7-phosphanorbornadiene(pentacarbonyl)-chromium
The reaction of dimethyl acetylenedicarboxylate with LM(CO)5 complexes (L = 1 -substituted-3,4-dimethyl-phosphole; M = Cr, Mo, W) provides an easy access to stable 7-phosphanornadiene complexes, the X-raycrystal of one of which is reported; the 31P resonance of these species appears at very low field (ca. 200–260 p.p.m.) and mass spectral and structural data suggest that they may be efficient generators
乙炔二甲酸二甲酯与LM(CO)5配合物(L = 1-取代的3,4-二甲基-膦; M = Cr,Mo,W)的反应可轻松获得稳定的7-膦酰基二烯配合物X射线晶体之一被报道;这些物质的31 P共振出现在非常低的电场(约200–260 ppm)下,质谱和结构数据表明,它们可能是仍然未知的末端次膦亚基络合物的有效生成剂。
