Benzaldehydeazines, p-anisaldehydeazines, and thiophene-2-carboxaldehyde azines react with excess chlorosulfonic acid to give corresponding disulfonyl chlorides 1,13, and 24. These were condensed with nucleophiles to give disulfonyl amino acid derivatives

Benzaldehyde- and o-, m-, p-anisaldehyde azines; thiophene-2-carboxaldehyde, and biphenyl-4-carboxaldehyde azines (1-8) reacted with excess chlorosulfonic acid to give the disulphonyl chlorides (1a-8a).These were condensed with amines and hydrazine to give 27 derivatives, (Table I) for biocidal evaluation.The orientation of sulfonation is discussed in relation to the stereoelectronic factors and the spectral data.Attempted chlorosulfonation of furan-2-carboxaldehyde azine (9) gave an impure product which could not be clearly characterized as the morpholidate derivative.
