  1. In this work, we examine the use of competitive 13 C kinetic isotope effects ( 13 C KIEs) on CO 2 reduction reactions that produce CO and formic acid as a means to formulate reaction mechanisms. The findings reported here mark a further advancement in the combined 13 C KIE measurements and theoretical calculations methodology for probing CO 2 conversion reactions.

  2. Abstract

    A transition metal‐free coupling reaction of benzylboronic esters and alkyl halides has been developed. Both alkyl bromides and alkyl iodides were found to be competent substrates with the nucleophilic boronate intermediate generated from the combination of benzylboronic ester and an alkyllithium. Good chemoselectivity was observed for the reaction with the alkyl bromide in substrates with a second electrophile present. Both secondary and tertiary benzylboronic esters were effective nucleophiles in the reaction with primary alkyl halides. Mechanistic observations are consistent with a radical mechanism.
