In sharp contrast to the transition metal-catalyzed diboration of alkynes with diboron species such as B 2 pin 2 , which affords vicinal cis -diborated alkenes, the organophosphine-catalyzed addition of B 2 pin 2 to alkynes proceeds under metal-free

Binary systems consisting of benzoyl peroxide (BPO) and diorganyl diselenide are effective in the selective benzoyloxyselenation of internal alkynes to afford the corresponding β-(benzoyloxy)alkenyl selenides in good yields. In contrast to internal
