substitution of deuterium for hydrogen at the terminal carbon atoms ( c-3 ) of tris-bp significantly decreased both the mutagenic response and the formation rate of 2- bromoacrolein . mass spectral analysis of the 2- bromoacrolein that was formed from the selectively deuterated analogs of tris-bp revealed that the primary mechanism for the formation of 2- bromoacrolein involves an initial oxidative dehalogenation at c-3 followed by a beta-elimination reaction .
