From: Cobalt-catalyzed hydrothiolation of alkynes for the diverse synthesis of branched alkenyl sulfides
a1 (0.50 mmol), 2 (0.25 mmol), CoBr2 (5 mol%), L1 (6 mol%), OMTS (1.2 eq.), LiOMe (2.5 eq.), THF (2.0 mL), 40 °C for 12 h, yields were determined by 1H NMR using 1,1,2,2-tetrachloroethane or 1,3,5-trimethoxybenzene as an internal standard, isolated yields are shown in parentheses. bL1•CoBr (5 mol%) instead of CoBr2 and L1. cAt 45 °C. dAt 35 °C.
