compounds. In contrast with existing methods that use more stable, but less reactive, organometallic species, there is efficient addition to esters, lactones and poorly reactive ketones. The addition of various RCF2Li compounds to a wide range of carbonyl electrophiles (aldehydes, ketones, acylsilanes, esters, and lactones) is reported. The reaction proceeds at very low temperature under Barbier conditions
