摘要

The structures of the parent compounds of phosphanyl-and arsanylboranes, H_2BPH_2 and H_2BAsH_2, were calculated by DFT-B3LYP methods. Such compounds have not previously been obtained preparatively. By applying the concept of Lewis acid/base stabilisation, [(CO)_5/W(H_2EBH_2·NMe_3)](E = P (3), As (4)) derivatives have been synthesised by the metathesis reactions between Li[(CO)_5WEH_2] and ClH_2BNMe_3 (E = P, As). Comprehensive thermodynamic studies on these systems verify the high stability of the Lewis acid/base stabilised complexes. Unexpected based on the thermodynamic calculations,UV radiation of the phosphanylborane 3 leads to the dinuclear phosphanido-bridged complex [(CO)_8W_2(mu-PHBH_2· NMe_3)_2] (5) by H_2 and CO elmination.
