Epichlorohydrin (ECH) is an effective linking group between tertiary amines and acid salts and is used to produce sulfonated amphoterics known as sulfobetaines. Sodium sulfite is reacted with epichlorohydrin in water to produce a solution of l-chloro-2-hydroxypropane sulfonate, which is further reacted with a tertiary amine to yield a quaternary ammonium group linked to the hydroxy-propane sulfonate, with sodium chloride as the primary by-product. Reaction of ECH with partially neutralized phosphorous or phosphoric acid produces an intermediate, which when reacted with tertiary amines yields the respective phosphitobetaines or phosphatobetaines. 

All experiments were at 70.0+0.1 with 1.20 0.01 mmol of 1, 6.04 x 10 mmol (5.0 mol %) of CoPcTs, pH 9.0-9.1 adjusted with 4.4 mmol of AMPSO [2-hydroxy-3-[2-hydroxy-1,1 -dimethylethyl)amino]- 1-propane-sulfonic acid] buffer. All reaction mixtures had a volume of 150 mL and were carried out at ca. 700 mmHg (ca. 40 mmHg less than atmospheric) pressure of dioxygen. Percent of phenol 1 consumed according to GC analysis. 3-4% yield of quinone 3 was found in addition to diphenoquinone 2.

Analysis of sulfonic acid species in sulfonated olefins. Kupfer and Kuenzler [108] reported the determination of acid species following partition between a 6.5% hydrochloric acid solution in 40% ethanol and a 1 1 (v/v) propan-2-ol-hexane mixture. The organic fraction contains alkenesulfonic and hydroxy-alkanesulfonic acids and the aqueous phase disulfonic acids and sulfato-sulfonates. The monosulfonic acids were converted to methyl esters and separated by column chromatography. To determine sulfatosulfonates the aqueous fraction was hydrolyzed and then partitioned and chromatographed. The separation is controlled using IR spectroscopy.

The classic preparation method of sulfo betaines utilizes the conversion of tertiary amines with propane sultone. Hydroxy sulfo betaines amino oxides are obtained from tertiary amines and chloro hydroxypropane sulfonic acid [32-34].

Photooxidation rates of propan-2-ol in aqueous Ti02 suspensions are reported to be increased by ultrasound radiation, an observation which has been rationalised in terms of mass transport of the substrate and activation of the solid catalyst. The value of the newly described photochemical rearrangement of 2-phenylthio-l,3-cyclohexanediols such as (69) to deoxysugars (70) which are in equilibrium with the closed form (71) has been illustrated by its application to the synthesis of (+)-m-rose oxide (72), and the same authors have also described the regioselective photorearrangement of 2-phenylthio-3-aminocyclohexanols (73) to deoxyazasugars (74) this has proved to be useful in the synthesis of various piperidines (75), amino-sulfones, -sulfoxides and -acids. Hydroxy(alkoxy)methyl radicals have been generated by photo-induced electron transfer. ...
