entry	variation from “standard conditions”	yield (%)
1	none	90 (88)
2	no applied voltage	<5
3	no light irradiation	<5
4	no DCA	<5
5	no pyridine	58
6	CFL (23 W) instead of blue LED	70
7	Al(+)/C(−) instead of Zn(+)/C(−)	65
8	undivided cell	37

^aCathodic chamber: 1 (0.4 mmol, 1.0 equiv), DCA (5 mol%), B₂pin₂ (2.0 equiv), pyridine (20 mol%), TBAPF₆ (0.15 M), CH₃CN (0.1 M); anodic chamber: TBAPF₆ (0.15 M), CH₃CN (0.1 M); cell voltage (U_cell) = 3.2 V; yields determined by ¹H NMR (isolated yield in parentheses).
