摘要：

Various stoichiometric combinations of PCl3 with DippNH(2) (Dipp = 2,6-di-isopropylphenyl) have been examined using P-31 NMR spectroscopy. The dehydrochloride coupling reaction is mediated by the moderate steric bulk of the Dipp substituent. Isolation procedures and characterization data are reported for the aminodichlorophosphine (1), the aminotetrachlorodiphosphine (4), and the dichlorophosphetidine (7). The observations offer new appreciation of dehydrochloride coupling products of halophosphines with primary amines.
