As a consequence of discrepancies in the literature, further investigations have been made concerning the identities of certain bisalkylthioalkenes and the possible existence of equilibria between the two isomers: R1CH:CH·CH(SR2)2⇌ R1CH(SR2)·CH:CH·SR2(R2= Et or Bun)

1-Chloro-3,3-, 2-chloro-3,3-, and 1-chloro-2,2-bisalkylthiobutanes spontaneously eliminate hydrogen chloride forming either bisalkylthiobutenes, usually with accompanying rearrangement, or trisalkylthiobutanes. They are thus much less stable than 3-chloro-1,1-bisethylthiopropane or -butane. Rearrangement without loss of hydrogen chloride has not been encountered.

Bis-alkylsulfonylmethane did react with alkyl p-toluenethiosulfonate giving bis-alkylsulfonyl-alkylmercaptomethane. Bis-alkylsulfonyl-halogenomethane was found to react with metal alkoxide giving original bis-alkylsulfonylmethane. It was also found that bis-alkylsulfonyl-dibromomethane readily reacts with silver nitrate giving the monobromo-compound while its dichloro-analog resists in the same condition

of the rates of bromination and acid dissociation constants of the disulphones (EtSO2)2-CHMe, (MeSO2)2CH2, (EtSO2)2CH2, (EtSO2)2CHPh, and (EtSO2)2CHBr. For (EtSO2)2CHMe the order with respect to bromine is between zero and unity, and it was possible to derive both rates of ionization (and of the reaction of the anions with acids) and velocity constants for the reaction between anion and bromine or tribromide
