Pd-catalyzed multialkynyl cross-coupling reaction performed with tetraalkynylindates generated in situ from the reaction of 1 equiv. of indium trichloride with 4 equiv. of organometallic reagents has been developed to produce symmetric as well as unsymmetric multialkynyl-substituted aromatic compounds in good-to-excellent yields. In these reactions, the four acetylide groups in the tetraalkynylindates transferred
一种有效的 Pd 催化的多炔基交叉偶联反应,由 1 当量的反应原位生成的四炔基进行。三氯化铟与 4 当量。已开发出有机金属试剂,以生产对称和不对称的多炔基取代的芳族化合物,产率非常好。在这些反应中,四炔基化合物中的四个乙炔基有效地转移到各种芳基溴化物上。
