One-pot transformation of cyclic phosphine oxides to phosphine-boranes by dimethyl sulfide-borane. Different types of cyclic phosphine oxides, such as tetrahydrophosphole oxide 1, phosphabicyclo[3.1.0]hexane-3-oxide 8 and phosphanorbornene 7-oxides 10 and 12 were efficiently converted to phosphine-boranes 2, 9, 11 and 13, respectively, by reaction with 4.4 equivalents of dimethylsulfide borane. The more strained hetero ring the starting phosphine oxide (in general 16) has, the easier to accomplish the change in the P-function is, that takes place through the corresponding phosphine intermediate (20). This is the first case that phosphine oxides (16) are transformed to phosphine-boranes (20) by the effect of borane, moreover in a one-pot reaction. It is also noteworthy that the imide carbonyl groups hi starting materials 10 and 12 were fully reduced by the borane to give 11 and 13, respectively.
