Fig. 2

Reaction conditions: alkenyl boronate (0.2 mmol), silane (0.24 mmol), 4CzIPN (0.5 mol%), EtO2CCH2SH (5 mol%), DIPEA (5 mol%) in MTBE (methyl tert-butyl ether) (0.1 M) under irradiation with 40 W, 456 nm LED light at room temperature for 12 h under argon. Isolated yields. Regioselectivity was determined by GC analysis of the crude reaction mixture. a1 mol% 4CzIPN, 10 mol% EtO2CCH2SH and 10 mol% DIPEA. bWith iPr3SiSH in THF (0.1 M). c4CzIPN (1 + 1 mol%), EtO2CCH2SH (20 mol%), DIPEA (20 mol%) under irradiation with 80 W, 456 nm LED light for 48 h. dWith iPr3SiSH in MeCN (0.1 M).
