As mentioned, the spectrum and amount of impurities formed during oxychlorination is much larger compared with direct chlorination. Some key impurities are listed below 1,1,2-trichloroethane (TCE), chloral (CCl3-CHO), trichloroethylene (TRI), 1,1- and 1,2-dichloroethylenes, ethyl chloride, chloro-methanes (methyl-chloride, methylen-chloride, chloroform), as well as polychlorinated high-boiling components. In particular, chloral needs to be removed immediately after reaction by washing because of its tendency to polymerization.

The chloro- and bromomethanes all decompose thermally by radical mechanisms. Shilov and Sabirova showed that methyl chloride decomposes at 850 °C mainly to hydrogen chloride, methane and acetylene in the mole ratio 3 1 0.5. The first-order rate coefficients for the decomposition, were found to be pressure-de-pendent, and the following reaction scheme was proposed... 

D-Berine methyl ester is converted into the IJ-triphenylmethyl derivative which, when heated in the presence of methane sulphonyl chloride, yielded the substituted ethylene-amine (2). Reaction of (2) with hydroxyl-amine and sodium methoxide gives the corresponding hydroxamic acid (3) This product is converted, by the action of hydrochloric acid, into D-a amiso-3-chloro-H-hydroxypropionamide (k), which undergoes cyclization to D-cycloserine (5) when treated with a strongly basic ion exchange resin.

ALKYL HALIDES Name functional group first, such as chlorine, which would become chloro, fluorine would become fluoro, and so on. Then name the hydrocarbon backbone one carbon would be methane, two carbons ethane, and so on. For exanple, chloro methane. Or name the hydrocarbon backbone first one carbon would become methyl, two carbons ethyl, and so on. Then name the functional group and add ide for an ending. For example, chlorine would become chloride, fluorine would become fluoride, and so on. An example is methyl chloride.

Metalation. Benzene reacts with alkaH metal derivatives such as methyl or ethyUithium ia hydrocarbon solvents to produce phenyUithium [591 -51 -5], CgH Li, and methane or ethane. Chloro-, bromo-, or iodobenzene will react with magnesium metal ia ethereal solvents to produce phenyHnagnesium chloride [100-59-4], C H MgCl, bromide, oriodide (Grignard reagents) (32). 

Acylation of (S)-2-pyrrolidinemethanol (1) with aroyl chlorides provides amides 2 which, when treated with base and iodomethane or chloro(methoxy)methane, furnish the corresponding methyl or methoxymethyl ethers 3.

Several different methods have been employed for the preparation of diazo(trimethylsilyl)meth-ane (1). At present, the best synthetic method seems to be the diazo transfer reaction between diphenylphosphoryl azide and (trimethylsilyl)methylmagnesium chloride.However, the product often contains (chloromethyl)trimethylsilane and hexamethyldisiloxane as impurities. This method can also be employed for the synthesis of diazo(triethylsilyl)methane and diazo(di-ethylmethylsilyl)methane. The diazo transfer reaction can also be carried out with (trimethyl-silyl)methyllithium and tosyl azide. Other methods are the silylation of diazomethane with (trimethylsilyl)trifluoromethanesulfonate or chloro(trimethyl)silane and the base-induced cleavage of A-nitroso-A-[(trimethylsilyl)methyl]urea or the related carbamate or acet-amide.2° =...
