Very little is yet known about the specific chemistry of 1,3,2-diaza-boracycloalkanes. At room temperature, these compounds add hydrogen halide readily in a 1 2 molar ratio 1>. In a similar manner, boron trihalide is added at low temperatures 13>. The solid addition products of the latter reaction decompose near room temperature with cleavage of the original B—N linkages presumably leading to linear products (Eq. 9).

Caution. l,3-Diaza-2-boracycloalkanes are moisture-sensitive and react readily with protonic materials. Alcohols, in particular, may occasionally cause an explosive solvolysis reaction on contact with these heterocycles. The compounds should be handled under dry inert gas (nitrogen or argon) to avoid their contamination. The possible toxicity of boron compounds has not yet been explored.
