Bephenium Bephenium, 3-hydroxy-2-naphthoat benzyldimethyl(2-phenoxyethyl) ammonia (38.1.37), is made by reacting the sodium salt of 3-hydroxy-2-naphthoic acid with benzyldimethyl(2-phenoxyethyl)ammonia chloride (38.1.36). This is in turn made from benzyl chloride and Af-(2-phenoxyethyl)dimethylamine (38.1.35), which is synthesized by reacting sodium phenolate with 2-dimethylaminoethylchloride [41,42]. 

The % ring substitution of the polymer is a critical factor in catalytic activity. Its importance was demonstrated clearly in Regen s first full paper on triphase catalysis 89). Catalysts 2 and 13 (2% CL) were active for cyanide displacement on 1-bromooctane (Eq. (3)) only at 21 % or lower RS (Table 3). Commerical anion exchange resins, polystyrenes highly substituted as benzyltrimethylammonium ions 2 or benzyldimethyl-(2-hydroxyethyl)ammonium ions 14, were inactive.

Biocidal applications. The use of quaternary ammonium salts in disinfecting systems for household and industrial cleaners has been known for many years [95, 96]. Alkyl-benzyldimethyl quaternaries, alkyltrimethyl quaternaries, and dialkyldimethyl quaternaries are the more commonly used biocidal quaternary ammonium salts [16]. Recently, dialkyldimethyl quaternary ammonium salts have received renewed attention as potential wood preservatives to replace the heavy metal types [97]. Metal-free wood preservative formulations containing dialkyldimethyl ammonium salts with non-halide anions, such as carboxylates, borates, and carbonates, have been developed [98, 99]. 

ZnTPP (Hambright, Washington D.C.), duroquinone (DQ) (Aldrich) and methyl viologen (MV+2) (BDH CHEMICALS) were used without further purification. The sodium salt of anthraquinone 2-sulphonate (AQS) (BDH CHEMICALS) was recrystalized from methanol. Benzyldimethyl-n-hexadecylammonium chloride (BHDC) (BDH CHEMICALS) was dried over P205 and stored under vacuum. The solvent, benzene (pro-analysis) (BDH CHEMICALS) was dried and distilled over sodium wire. Stock solutions of reversed micelles were prepared by adding dropwise the calculated amount of water to the appropriate solution of BHDC. The surfactant concentration used throughout the experiments was 0.1 mol dm 3.

When non-chiral benzyldimethyl(piperidinomethyl)silane is Uthiated, the resulting alkyllithium 1 forms a tetramer in the solid state, not being coordinated by a further external solvent molecule. The carbanionic unit is fully planar, the sum of the bond angles amounting to 360° (Fig. 1) [Ig]. 

The relative product ratios of the regioisomers 6 and rac-5 varied according to the reaction conditions. The highest (relative) amount of compound 6(11 1 product ratio) was found using the polar solvent THF, and the product ratio most in favor of rac-5 (2.4 1) was found in the non-polar solvent n-pentane. We made a similar observation during the lithiation of benzyldimethyl-(piperidinomethyl)silane [Ig]. When benzyldimethyl(piperidinomethyl)silane was treated with 1 equiv of fert-butyllithium in n-pentane or toluene at -90 °C, one of the methyl groups was lithiated selectively. Selective metalation of the benzyl position under formation of 1 occurs only when the same reaction is carried out in a polar donor solvent, such as THF.
