[a]

Conditions: amine 1 (1.0 equiv), vinyl bromide 2 (1.1–2.0 equiv), NaO t-Bu (1.2 equiv), Pd2(dba)3 (1 mol%), P(2-furyl)3 (4 mol %), toluene (0.25 M), 60–110 °C.

[b]

Product ratios refer to the isolated material, as judged by 1H NMR analysis. Product ratios and yields refer to the average of two or more experiments.

[c]

This material contained ~5 % of 5a as an inseparable impurity.

[d]

This material contained ~10 % of 5d as an inseparable impurity.
