A mild platinum-catalysed method for the formation of free amidines from the reaction of amines and trichloroacetonitrile in nonpolar solvents has been developed. This protocol provides access to novel amidines that in some cases (4b–d) cannot be synthesised via the direct reaction of amines and halogenated nitriles.
已开发出一种温和的
铂催化方法,该方法可在非极性溶剂中由胺与
三氯乙腈的反应形成游离am。该方案可提供新颖的am,在某些情况下(4b - d)不能通过胺与卤代腈的直接反应来合成。
