Sodium />-toluene sulfinate

The Hquid is basically a methacrylate monomer having a suitable inhibitor to ensure adequate shelf life. A/Ai -Dimethyl-/)-toluidine [99-97-8] is probably the most common polymerization accelerator although A/A/-bis(2-hydroxyethyl)- -toluidine and/or a sulfinate salt, eg, sodium -toluene sulfinate [873-55-2], also maybe used. 

To 1 1. of boiling water in a 3-I. beaker or large evaporating dish (Note 1) is added 150 g. of mercuric chloride to this mixture is then added, with good stirring, 116 g. of sodium />-toluene-sulfinate (Vol. II, p. 89). A thick, white, curdy precipitate forms at once (Note 2), and in a short time sulfur dioxide is evolved copiously. The heating and stirring are continued until no more sulfur dioxide is evolved, which requires about two hours. 

Os(II) complexes of tosylmethylisocyanide react with aldehydes and ketones in the presence of sodium methoxide, producing cyclic carbene complexes (66). Compound 32 undergoes a rapid reaction with benzal-dehyde and NaOMe, yielding the oxazol-2-ylidene complex 33 and eliminating p-toluene sulfinic acid (66) ...

Preparation of 1 -butyl-3-p-tolylsulfonylurea by the reaction of butyl-carbamoyl azide with sodium p-toluene sulfinate [104]. 

Related work by Culvenor and oo-workers28 hu dealt with addition of sodium salts of arylaulfinic adds, which attack epoxide rinps in the same manner as sodium sulfite. Product thereby obtained are Bulfones. Examples of this interesting reaction include the condensation of sodium benxenesulfinate with epichlorohydiin. and of sodium toluene-p-sulfinate with propylene oxide andglycidol (Eq. 6114). 

The overall rate of polymerization Rp of barium acrylate (BA) polymerization sensitized by MB in the presence of varying amounts of j>-toluene sulfinate sodium sslt (PTSS) was shown to depend on the square root of the absorbed light intensity and to exhibit a complex second order dependence on the concentration of sulfinate and monomer (43). The latter dependence was shown to result from a desensitization process described by eq. 16 in which PTSS undergoes Michael addition to the acrylate monomer. 

Early results with crotyl chloride and the sodium salt of toluene sulfinic acid in the presence of DIOP gave the allyl sulfone in 88% ee and with a ratio of 5.3 1 for the regioisomers favoring the chiral product [113]. A BPPFA analogue com-... 

The alkylation reaction in a two-phase system was also extended to various heteronucleophiles [11]. Secondary amines (morpholine, benzyhnethylamine, etc.) as well as primary amines (n-butylamine, 2,2-diethylpropargylamine, cyclohexyl-amine, a-methylbenzylamine, etc.) react for example with ( )-cinnamyl acetate to give only the monoaUylated product in quite good yields [Eq. (2)]. The water-soluble nucleophiles sodium azide and sodium p-toluene sulfinate react also under these conditions, giving the corresponding aUyl azide and allyl p-toluene sulfone in 92 and 95% yield, respectively.

Ally lie substitution of a variety of substrates (such as allyl carbonates or acetates) with carbon- or heteronucleophiles (201) was shown to occur under mild conditions (50-80°C) on the catal3rtic effect [Pd(OAc)2l -I- TPPTS (Scheme 34). In many cases, there was no need for an external base however, reactions of allyl acetates required the presence of (C2H5)3N or l,8-diazabicyclo-5,4,0-undec-7-ene (DBU). Primary and secondary amines, as well as sodium azide and p-toluene sulfinate, also reacted cleanly. The use of butyronitrile or benzonitrile allowed easy separation and recycling of the catalyst. 

Depending on the solvent, different reaction products form when alkenes react with iodine in presence of cerium(IV) triflate 1,2-hydroxy iodides in water, 1,2-alkoxy iodides in alcohols and 1,2-acetoxy iodides in acetic acid (Iranpoor and Shekarriz, 2000).
