Tungsten (0) complexes trans-LL′W(CO)4 (L ≠ L′: i-Pr3P, Ph3P, (Me2N)3P, (i-PrO)3P (PhO)3P) fall into two categories with respect to their photochemistry. Compounds of type A, which contain at least one strongly donating phosphine ligand, lose one of the axial phosphines upon irradiation. Of the two different phosphines, one is always lost preferentially, with the photochemical lability increasing in

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
