Reactions of LiA1H4 with sufficiently sterically hindered (R2N), PCl derivatives (R= isopropyl and ethyl but not methyl) in diethyl ether give the corresponding (R2N), PH derivatives as air- sensitive, vacuum-distillable liquids. Analogous reactions of LiAlH, with sufficiently sterically hindered heterocycles (CH,),(NR), PCl (R= tert-butyl, n= 2 and 3; R# methyl, n# 2) give the corresponding heterocyclic PH derivatives (CH,),(NR), PH. The dialkylamino groups in ( ...
