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% Safety and Hazards Pictogram(s)SignalDangerGHS Hazard StatementsH225 (100%): Highly Flammable liquid and vapor H315 (74.51%): Causes skin irritation H319 (74.51%): Causes serious eye irritation H332 (19.61%): Harmful if inhaled H335 (100%): May cause respiratory irritation H361 (23.53%): Suspected of damaging fertility or the unborn child H400 (23.53%): Very toxic to aquatic life H410 (23.53%): Very toxic to aquatic life with long lasting effects Precautionary Statement CodesP203, P210, P233, P240, P241, P242, P243, P261, P264, P264+P265, P271, P273, P280, P302+P352, P303+P361+P353, P304+P340, P305+P351+P338, P317, P318, P319, P321, P332+P317, P337+P317, P362+P364, P370+P378, P391, P403+P233, P403+P235, P405, and P501(The corresponding statement to each P-code can be found at the GHS Classification page.)
