and N-heterocyclic carbene (NHC)-boryl radicals were found to promote selective mono- or dihydrodechlorination of trichloroacetamides and acetates upon treatment with dilauroyl peroxide (DLP) as radical initiator and thiophenol as polarity reversal catalyst. Substituting the hydrogen atom donor, i. e. Lewis base-borane, to its deuterated counterparts promoted mono- or dideuterodechlorination instead
