Table 3. Scope of (E/Z)-dienes for stereoconvergent hydrosilylation reactions ^a .

^aConditions: (E/Z)-diene (0.400 mmol), PhSiH₃ (0.500 mmol), Co(acac)₂ (4.0 μmol), xantphos (4.0 μmol), and THF (1 mL) at rt for 6 h; yield of isolated product; 1,2/1,4 ratios refer to 1,2-/1,4-hydrosilylation, the ratios in brackets are the E/Z ratios of the conjugated butadiene reagents.

^bReactions were conducted at 5 °C for 24 h.

^c3 mol% catalyst at rt for 48 h.
