The palladium-catalyzed direct alkenylation of alkyl chain-substituted tetrathienoacenes has been developed under mild conditions. This effective and feasible approach could be readily applied to a variety of dialkenylated tetrathienoacenes using different functionalized alkenes as the coupling substrates, such as linear α,β-unsaturated esters, alkenyl phosphonate, sulfone, acrolein, asn styrene derivatives
已在温和条件下开发了钯催化的烷基链取代四噻吩并并苯的直接烯基化反应。这种有效且可行的方法可以很容易地应用于使用不同功能化烯烃作为偶联底物的各种二烯基化四噻吩并苯,例如线性α,β-不饱和酯,烯基膦酸酯,砜,丙烯醛,asn 苯乙烯衍生物。
