Based on solid state structure-reactivity correlation studies and on deuterium labeling experiments, it is concluded that the photochemical formation of thiobenzanilides 2a–d from monothioimides 1a–d does not involve initial γ-hydrogen atom abstraction as originally suggested in the literature. Alternative mechanistic possibilities are presented and discussed.
their α,β-unsaturated counterparts is reported. The reaction does not require strong base/acid or sulfur/selenium and oxidant reagents and can be carried out at room temperature through a simple one-step operation. The protocol exhibits great scalability and functional group tolerance. The reaction mechanism has been investigated through deuterium labeling experiments, radical clock, radical capture
