以铜为催化剂,结合不同的反应条件,分别阐述了酰胺、胺、唑类化合物和硫化物与卤代烯烃的交叉偶联反应,从而分别得到了各种烯酰胺、烯胺、N-烯基唑类化合物和烯基硫醚化合物.上述亲核试剂与1,4-二卤-1,3-二烯化合物反应,经过两次乙烯基化反应,可以高效地得到各种取代的吡咯和噻吩衍生物.进一步阐述了N—H键以及其邻位C—H键也能够和1,4-二卤-1,3-二烯反应,生成唑并吡啶衍生物.
With copper as catalyst, combined with different reaction conditions, the cross-coupling reactions of amides, amines, azoles and sulfides with halogenated olefins were described respectively, and various enamides, enamines, N-alkenyl Azole compounds and alkenyl sulfide compounds The above nucleophiles react with 1,4-dihalo-1,3-dienyl compounds, and after two vinylation reactions, various substituted pyrrole and thiophene Derivatives further elaborate that the N-H bond and its ortho C-H bond can also be reacted with 1,4-dihalo-1,3-diolefin to give an oxazopyridine derivative.
