Yield:100-13-0 91% ，619-93-2 7%

Reaction Conditions:

with potassium fluoride;Pd (0.83 wt%)/MgO in N,N-dimethyl-formamide at 130; under 1500.15 Torr; for 9 h;Inert atmosphere;Hiyama Coupling;Reagent/catalyst;Time;

Steps:

6.2.1 Preparation of styrene derivatives (3a-h)

General procedure: A mixture of organohalides (1a-h) (0.25mmol), vinysilanes 2a (0.3mmol) or 2c (0.075mmol), potassium fluoride (0.6mmol), and supported palladium NPs catalyst (Pd/substrate ratio 1mol%) was suspended in DMF (1ml). Then, the flask was evacuated under vacuum and refilled with argon. The evacuation/refilling cycle was repeated three times (pressure 2bar). The mixture was stirred at 130°C, and the reaction was monitored by GC and GC-MS. The reaction was performed for the time required ranging from 1.5 to 24h, to obtain the maximum yield of 3a-h products.
