Cascade alkylation and deuteration with aryl iodides via Pd/norbornene catalysis: an efficient method for the synthesis of congested deuterium-labeled arenes†
Abstract
An efficient approach for synthesizing congested deuterium-labeled arenes via cascade alkylation and deuteration with aryl iodides has been disclosed. We found that the adoption of sodium formate-d as a deuterium source is the key for achieving high deuterium incorporation >98%.
