Route of Synthesis (ROS)
| Conditions | Yield |
| With palladium(II) acetylacetonate; potassium fluoride In N,N-dimethyl-formamide at 130℃; under 1500.15 Torr; for 3h; Reagent/catalyst; Time; Hiyama Coupling; Inert atmosphere; Experimental Procedure 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. | 93% |
