t BuOK-triggered bond formation reactions.

Recently, inexpensive and readily available t BuOK has seen widespread use in transition-metal-free reactions. Herein, we report the use of t BuOK for S-S, S-Se, N[double bond, length as m-dash]N and C[double bond, length as m-dash]N bond formations, which significantly extends the scope of t BuOK in chemical synthesis. Compared with traditional methods, we have realized mild and general methods for disulfide, azobenzenes imine etc. synthesis.
