The benzoate of V was prepared by reaction with benzoyl chloride in the presence of pyridine (as described by Meyer arid Bernhauer') and after recrystallization from ethanol and isooctane was found to melt a t 67-68'. It will form HCl when in contact with water - so a lot of its chemistry with organic molecules will originate from that process. In water, this is attached to a hydrogen atom. 3 The reaction between the thioglycolate 3 and SO 2 Cl 2 is exothermic, as is the reaction .
