Combined, these two factors leave no doubt about the regioselectivity of the alkylation. Did the J values lead you to the right answer, or did you rely on the CH2 shift? Let’s discuss in the comments! 👇

Rhodium-catalyzed hydroselenation of unsymmetric 1,3-dienes with 3,4-Markovnikov regioselectivity Catalytic hydroselenation of alkenes represents one of the most direct and efficient methods for organoselenide synthesis. In this study, we report a highly regioselective Rh-catalyzed hydroselenation...
