A series of new soluble N-substituted poly(β-haloallylanilines), namely poly[N-(2-chloroprop-2-en-1-yl)aniline] (NPC), poly[N-(2-chloroprop-2-en-1-yl)-2-methylaniline] (NPT) and poly[N-(2-chloroprop-2-en-1-yl)-2-methoxyaniline] (NPA), were synthesized by oxidative polymerization in 1M HCl medium using (NH4)2S2O8 as the oxidant.

Effect Of Solvent

1. Whereas the second-order rate constants for the reaction of the thiolate ion of 2-mercaptoethanol with 4,4'-dipyridyl disulphide (k4PDS) and with 5,5'-dithiobis-2-nitrobenzoate dianion increase with decreasing dielectric constant of the solvent, or remain unchanged, the rate constant for the analogous reaction with 2,2'-dipyridyl disulphide (k2PDS) decreases. This anomalous solvent effect and other unusual physicochemical properties of 2,2'-dipyridyl disulphide are discussed. 2. The differential effect of solvent on the reactions of thiolate ion with the 2,2'- and 4,4'-dipyridyl disulphides is shown to provide a method of characterizing solvent environments of thiol groups in proteins by a reactivity-probe method that should not suffer from the usual drawback associated with the existence of steric or binding effects of unknown magnitude. Application of the method to ficin (EC 3.4.22.3) suggests that its active-centre thiol group resides in a relatively hydrophobic environment. 3. The pH-k profile for the reaction of ficin with 4,4'-dipyridyl disulphide is reported.
