Entry	Change from initial conditions[b]	Yield of 2 a [%][c]
1	no change	54
2	nBu4NBr (c=0.3 mol l −1) as conducting salt[d]	55
3	I =8 mA [e]	72
4	I=6.5 mA or 5 mA	71
5	I=2.5 mA	43
6	T=0 °C	36

[a] Reactions were performed in a divided cell on a 0.25 mmol scale with a substrate concentration of 36 mmol l ⁻¹. [b] Initial conditions: 3.0 equiv TMSCl, 0.3 mol l ⁻¹ nBu₄NClO₄, DMF, 23 °C, 10 mA, 2.0 F mol⁻¹, CuSn₁₇Pb (leaded bronze) cathode, graphite anode. [c] Yield determined by GLC of the unpurified reaction mixture with mesitylene as internal standard. [d] This change was kept for entries 3–7. [e] This change was kept for entries 6–8.
