四羰基wolfram-komplexe mit zwei unterschiedlichen供体配体:II。光化学配体取代反式-双(膦)-共轭复合物
摘要:
钨(0)配合物的反式-LL'W(CO)4(L≠L':ⅰ-PR 3 P,博士3 P,(ME 2 N)3 P,(I-PRO)3 P(PHO)3 P )就其光化学而言可分为两类。包含至少一种强供体膦配体的A型化合物在辐照时会丢失其中一种轴向膦。在两种不同的膦中,总是优先丢失一种,随着(Me 2 N)3 P <(i-PrO)3 P 3 P <(PhO)3 P

spectral data of 38 complexes of the type cis - and trans -W(CO) 4 (PR 3 )(L) are presented. The much larger chemical shift range for a particular phosphine in cis compounds is shown to arise mainly from steric interactions. 1 J(W–P) depends on the electronegativity of the substituents at phosphorus and the nature of the trans ligand. A trans influence series for octahedral tungsten(O) is derived: SbPh
