WebGrignard reagents are prepared by reacting either alkyl or alkenyl halides (chloro, bromo, or iodo, never fluoro) with magnesium metal. The reaction occurs on the surface of the Mg and involves single‐ electron transfers, radical ions, surface‐bound species, and possibly free radicals as well. WebThe Grignard reagents were submitted to addition reaction with carbonyl compounds and allylation with the cyclic monoacetate to afford the propargyl-type products selectively. Furthermore, the product from the monoacetate was transformed to an acetylene analogue of 2-(5,6-epoxyisoprostane A2)phosphorylcholines.
