The nickel-catalyzed hydroarylation of 1,3-dienes with arylboronic acids using a secondary homoallyl carbonate as a surrogate for the 1,3-diene and hydride source has been developed. The synthetic strategy allowed an efficient access to a wide array of hydroarylation products in high yields with high functional group compatibility without the use of an external hydride source.

已经开发了使用仲碳酸烯丙基碳酸酯作为1,3-二烯和氢化物源的替代物,用芳基硼酸进行镍催化的1,3-二烯的氢芳基化反应。合成策略允许以高收率和高官能团相容性高效获得各种加氢芳基化产物,而无需使用外部氢化物源。机理实验表明,烯烃定向氧化加成和随后的β-氢化物消除将是该转化过程中的关键过程。
