The chemoselectivealkylation and olefination of alkylnitriles with alcohols have been developed by simply controlling the reaction atmosphere. A binuclear rhodium complex catalyzes the alkylation reaction under argon through a hydrogen‐borrowing pathway and the olefination reaction under oxygen through aerobic dehydrogenation. Broad substrate scope is demonstrated, permitting the synthesis of some

The first switchable α-olefination and α-alkylation of nitriles with primary alcohols catalyzed by a well-defined base transition-metal Co complex was presented. A broad variety of nitriles and primary alcohols are selectively and efficiently converted to the corresponding products by this method. It is noteworthy that the transformation is environmentally benign and atom efficient with H2 and H2O
首次提出了在明确的碱性过渡金属 Co 配合物催化下,腈与伯醇的可切换 α-烯化和 α-烷基化。通过这种方法,多种腈和伯醇被选择性地、高效地转化为相应的产物。值得注意的是,该转化对环境无害且原子效率高,H 2和 H 2 O 是唯一的副产物。
