E‐Substituted styrene derivatives are synthesized from terminal olefins and aryl Grignard reagents through TiIV‐mediated oxidative coupling (see scheme). Substrates include homoallylicalcohols containing a range of functional groups and substituted aryl Grignard reagents. The reaction may proceed through aryltitanation followed by β‐hydride elimination; reductive elimination of arene occurs from a
E取代的苯乙烯衍生物是通过Ti IV介导的氧化偶合反应由末端烯烃和芳基格氏试剂合成的(参见方案)。底物包括含有一系列官能团的均烯丙基醇和取代的芳基格氏试剂。该反应可通过芳基钛化反应继之以β-氢化物消除进行。从Ti IV H(芳基)中间体发生芳烃的还原消除。
