Abstract

Organometallic intermediates have been proposed in the dechlorination sequence based on UV–visible absorbance data, 5,7,8 mass spectrometry data, 9 mass balance considerations, 10 and kinetic evidence. 11 This hypothesis is bolstered by studies that report the reaction of low-valent metal complexes with halogenated ethylenes, in which chlorovinyl complexes are formed. 12–22 The importance of the putative organometallic intermediates is not known. ...
