Abstract

A set of diboryldiborenes are prepared by the mild, catalyst-free, room-temperature diboration of the B-B triple bonds of doubly base-stabilized diborynes. Two of the product diboryldiborenes are found to be air- and water-stable in the solid state, an effect that is attributed to their high crystallinity and extreme insolubility in a wide range of solvents.

摘要

通过对双碱稳定的乙硼炔的B-B三键进行温和、无催化剂、室温下的二硼化反应，制备了一系列二硼基二硼烯。发现其中两种产物二硼基二硼烯在固态下对空气和水稳定，这归因于它们的高结晶度以及在多种溶剂中的极端不溶性。
