Reactions of N-bromohexamethyldisilazane (Me3Si)2NBr with Si-H compounds of the general formula RR'2SiH yield up to 90% of unsymmetrical disilazanes (Me3Si)2NSiRR2 and bromotrimethylsilane. An unexpected solvent effect on the reaction conditions is revealed: In benzene the products are formed already on mixing, whereas in cyclohexane, under UV irradiation only.

Reaction of N-bromohexamethyl disilazane (Me3Si)2NBr with substituted triorganyl silanes R1R2R3SiH results in asymmetric disilazanes Me3SiNHSiR1R2R3 and bromination product, bromotrimethyl silane Me3SiBr. The reaction has demonstrated an unusual dependence on specific solvation. In benzene, bromination occurs immediately after mixing of the reagents, while in cyclohexane, the reaction products are formed only under UV-irradiation. Application of photoinduced CIDNP method has shown that the mechanism of bromination of triorganyl silanes is comprised of a series of consecutive radical stages involving N-centered disilazanyl (Me3Si)2N{radical dot} and Si-centered silyl R1R2R3Si{radical dot} radicals.
