Many reactions of fluorinated organics with metal halides result in the replacement of fluorine with halogen A general route to 1,1,1-trichloro- or tribromo-fluoroalkanes involves treating primary fluoroalkyl iodides with aluminum trichloride or aluminum tribromide [74], Benzylic [75, 76] or vinylic [72] fluorine can be exchanged for chlorine when treated with aluminum trichloride... 

During an attempt at destroying benzyl cyanide residues with sodium hypochlorite, a detonation was caused that was probabiy due to the formation of nitrogen trichloride. However, it might be asked if it was not due to the nitrile group oxidation by the hypochlorite present. 

Synthetic routes that access appropriately substituted thienobenzazepines are also quite important for medicinal chemistry stracture activity relationship studies, and many involve similar bond connectivity strategies. One notable example employs the use of conunercially available 4-methyl-3-nitrophenol (Scheme 6.3). Methylation of the phenol followed by bromination, hydrolysis, and oxidation of the benzylic alcohol afforded aldehyde 9 in quantitative yield. Treatment of this aldehyde with 5-lithio-2-methylthiophene provided, after dehydroxylation, nitro intermediate A in good overall yield. Reduction of the nitro functionality and treatment with phosgene presented the corresponding isocyanide which upon cychzation using aluminum trichloride in a Friedel-Crafts fashion afforded the... 

Use of sodium hypochlorite solution to destroy acidifed benzyl cyanide residues caused a violent explosion, thought to have been due to formation of nitrogen trichloride. 

M-Benzyl-O-methyl-L-serinoate (173) was condensed with phosphoryl trichloride giving cyclic chloridate 174 that reacted with the Tegafur derivative 175 with the formation of almost equal amounts of 2-alkoxy-l,3,2 oxazaphospholidine-2-oxides 176a and 176b (Scheme 49) [80],... 

Both benzylic and secondary aliphatic alcohols are reduced with the combination of Ph2ClSiH and a catalytic amount of indium trichloride. This combination... 

Treatment of ethenes 158 with trithiazyl trichloride afforded 1,2,5-thiadiazoles 159 in moderate to good yields (Equation 32 Table 10). The reaction, however, suffers from the possibility of chlorination at allylic or benzylic positions, in particular if excess trimer is used. 

From phosphorus trichloride, benzyl alcohol and 2 mol. of a tertiary base, dibenzyl hydrogen phosphite (XIV), is obtained which on treatment with chlorine or a chlorinating agent (e.g. sulphuryl chloride)4 gives the phosphorochloridate (XV). Although not isolated, (XV) is almost certainly obtained by treatment of (XIV) with a polyhalogen hydrocarbon because reaction in the presence of an alcohol or of a primary or secondary amine gives a triester (XVI) or a phosphoramidate. 

Antimony(III) trichloride can be used as a catalytic mediator in the electroreduction of carbonyl compounds. The advantage of the procedure is illustrated by the selective reduction of acetophenones (497), leading to the corresponding benzylic alcohols (498) (Scheme 173) [575]. The electroreduction is performed in an EtOH/BuOH(l/1.5)-aq.HCl-(Pt/Pb) system in the presence... 

Olefmic benzyl ethers can also be submitted to ethercychzation with aryltellurium trichlorides. The yields and the reaction times are close to those observed for the cycliza-tion of the corresponding alcohols. The stereochemistry of the reaction is low. ... 

Typical procedure A mixture of the benzyl ether (0.246 g, 1 mmol) and p-phe-noxyphenyltellurium trichloride (0.403 g, 1 mmol) in anhydrous chloroform (15 ml) was stirred for 30 min at room temperature, then the solvent was evaporated and the residue was filtered through a column of silica gel eluting with chloroform. Evaporation of the solvent in a rotatory evaporator followed by recrystallization of the residue from chloro-form/petroleum ether and washing several times with petroleum ether gave 0.50 g (97%) of the product, m.p. 108-110°C. 

A mixture of titanium trichloride and 0.33 equivalent of lithium aluminum hydride in dimethoxyethane causes coupling of the benzyl residues benzyl alcohol thus affords bibenzyl in 78% yield [204],... 

Diazaarsoles (R = Me, Et, Ph) result from the condensation of the phenylhydrazone of a methyl or benzyl ketone with arsenic trichloride in the presence of triethylamine (Scheme 8) <73TL4503, 74TL1977). Phenylhydrazones of cyclopentanone, cyclohexanone, norbornanone, nor-bornenone, and steroid ketones react as well.
