As in the previous examples, borazine (1.618 g, 20.1 mmol) and 2-butyne (20 mmol) were reacted in the presence of RhH(CO)(PPh3)3 (0.0165 g, 0.018 mmol) for four hours at room temperature. Fractionation of the resulting reaction mixture gave 0.2702 g (2.01 mmol) of B-butenyl-borazine stopping in a -55° C. trap. GLC analysis of the product indicates that it is composed of a 3:2 mixture of B-trans-(2-cis-butenyl)borazine and B-trans(1-butenyl)borazine. Pure samples of each isomer were prepared by preparative G.L.C.
