The formation of four products of the type Me3C(Me3Si)N=BH-N(CMe3)=BR2' [BR
2' = B(CHMeiPr)(2) (1), B(c-C6H11)(2) (2), B(C8H14) (3), B(O2C6H4) (4)] fro
m the iminoborane Me3C(Me3Si)N - B double bond N(CMe3) and the hydroboranes
(R-2'BH)(2) is described. Crystal structure analysis reveals the molecule
1 to have an N=B-N=B backbone with two orthogonal N=B bond planes and, henc
e, no conjugation between the two B-N double bonds.
