Tertiary Amine-Containing Copolymers. Copolymers based on DMAEMA (dimethylaminoethyl methacrylate) in either free amine form or quaternized with diethyl sulfate or methyl chlonde have achieved commercial significance as fixatives in hair-styling formulations, especially in the well-publicized mousses" or as hair-conditioning shampoo additives.

The use of penodic acid oxidation m structure determination can be illustrated by a case m which a previously unknown methyl glycoside was obtained by the reaction of D arabmose with methanol and hydrogen chlonde The size of the nng was identified as five membered because only one mole of penodic acid was consumed per mole of glycoside and no formic acid was produced Were fhe nng six membered fwo moles of penodic acid would be required per mole of glycoside and one mole of formic acid would be produced... 

The pyrolysis of sodium chlorodinuoroacetate is still a widely used, classical method for generating difluorocarbene, especially with enol and allyl acetates [48, 49, 50, 51] (equation 21) A convenient alternative that avoids the hygroscopic salt uses methyl chlorodifluoroacetate with 2 equivalents of a lithium chlonde-hexa-methylphosphoric triamide complex at 75-80 °C in triglyme [52], Yields are excellent with electron-rich olefins but are less satisfactory with moderately nucleophilic alkenes (4-5% yields for 2-bulenes)... 

Copolymers of acrylonitrile and methyl acrylate and terpolymers of acrylonitrile, styrene, and methyl methacrylate are used as bamer polymers. Acrylonitrile copolymers and multipolymers containing butyl acrylate, ethyl aciylate, 2-ethylhexyl acrylate, hydroxyethyl acrylate, methyl methaciylate. vinyl acetate, vinyl ethers, and vinylidene chlonde are also used in bamer films, laminates, and coatings. Environmentally degradable polymers useful in packaging are prepared from polymerization of acrylonitrile with styrene and methyl vinyl ketone.

One Sanofi synthesis of enantiomerically pure (+)-clopidogrel (2) utilized optically pure (R)-(2-chloro-phenyl)-hydroxy-acetic acid (20), amandelic acid derivative, available from a chiral pool.18 After formation of methyl ester 21, tosylation of (R)-21 using toluene sulfonyl chloride led to a-tolenesulfonate ester 22. Subsequently, the SN2 displacement of 22 with thieno[3,2-c]pyridine (8) then constructed (+)-clopidogrel (2). Another Sanofi synthesis of enantiomerically pure (+)-clopidogrel (2) took advantage of resolution of racemic a-amino acid 23 to access (S)-23.19 The methyl ester 24 was prepared by treatment of (S)-23 with thionyl chlonde and methanol. Subsequent SN2 displacement of (2-thienyl)-ethyl para-toluene-sulfonate (25) assembled amine 26. 

The second point to explore involves carbocation stability. 2-Methyl-propene might react with 11+ to form a carbocation having tluee alkyl Mib stituents (a tertiary ion, 3°), or it might react to form a carbocation having one alkyl substituent (a primary ion, 1°J. Since the tertiary alkyl chlonde, 2-chloio 2 methy propanc, is the only product observed, formation of the tertiary cation is evidently favored over fonnation of tlie primary cation. Thertnodymuihc measurements show that, indeed, the stability of carbocations increases with increasing substitution so that the stability order is tertiary > secondary > primary > methyl.
