摘要

Reactions Of (C6H5)2P(O)C1 and C6H5P(O)C12 With C6F5NH2 yielded the newphosphoranes (C6H5)2P(O)NHC6F5, 1, and C6H5P(O)(NHC6F5)2, 2. When C6H5P(O)C12 was reacted with 2-fluoroaniline, the 1,3,2,4diazadiphosphetidine C6h5P(O)NC6FH42, 3, formed, while with C6H5PC12, C6F5NH2 give the new cis-1,3,2,4-diazadiphosphetidineC6H5PNC6F52,4. Compoundsl,2,3, and 4 have been characterized by spectral data (1H, 19F and 3 1p NMR, IR and MS) and elemental analysis. In addition, 1 has been characterized by single crystal X -ray crystallographic analysis. Lattice parameters and space group information are as follows: a = 9.958(2)A, b = 5.201(2)A, c = 31.603(6)A, B = 94.82(2)A, monoclinic, P21/n, Z = 4. ne structure was solved and refined by direct methods to R = 0.0789 and rw = 0.0936 for 2577 independent reflections. The molecule has both P and N with distorted tetrahedral coordination and has an approximate C2 symmetry axis. phosphoranes, cyclic phosphorus -nitrogen compounds, cis -dialkyldiaza phosphetidines; x-my crystal structure of fluoroaromatic phosphorane.
