General Introduction

Although transient disilenes were first reported in the 1970s, the first solid, stable derivative was not synthesized until 1981. There are many useful reviews available that describe the synthesis, physical properties, and reactivity of disilenes.[‌1‌,‌2‌] The key to synthesizing stable derivatives of this class of compounds is the use of bulky substituents; an increase in the size of the substituent leads to an apparent increase in the stability of the disilene. Stable aryl-, alkyl-, silyl-, amino-, and alkoxy-substituted disilenes have been synthesized. The development of facile methods for the synthesis of stable disilene derivatives has resulted in extensive research on both their physical properties and their reactivity.
