摘要：

Reactions of tricyclic hydrophosphorane, (4S, 9S)-4, 9-diethyl-2, 11-dioxa-5, 8-diaza-1 lambda(5)-phospha-tricyclo[6.3.0.0(1.5)]undecane (1), with BF(3)xEt(2)O and with ZnCl2 under mild conditions have been investigated. The phosphorane ligand in the complexes obtained (2 and 3, respectively) was found to maintain its tricyclic structure, while the BF3 and ZnCl2 groups coordinate to the apical nitrogen and oxygen atoms of the trigonal bipyramid of phosphorane. The structure of the complexes has been evaluated by the following set of methods: IR and NMR B-11, C-13, F-19, P-31 spectroscopy mass-spectrometry, X-ray photoelectron spectroscopy, ultracentrifugation and elemental analysis. Spectral peculiarities and dynamic behavior in different solvents of compound 2 have been examined in detail.
