Product introduction

4-溴苯乙烯是对卤代苯乙烯衍生物。只有当最低频率的扭转运动发生在大约80cm-1处时，4-溴苯乙烯的质子谱才显示出与平面基态结构一致的偶极耦合。在乙酸钠和Hermann催化剂存在的情况下，其可在N,N-二甲基乙酰胺中与2-溴-6-甲氧基萘进行Heck反应，得到二芳基乙烯。 4-Bromostyrene is a para-halogenated styrene derivative. The proton spectra of 4-bromostyrene exhibits dipolar couplings consistent with planar ground state structures, only if the torsional motion of lowest frequency occurs at about 80cm-1. It undergoes Heck reaction with 2-bromo-6-methoxynaphthalene in the presence of sodium acetate and Hermann′s catalyst in N,N-dimethylacetamide to afford diarylethene.
