Via such a gas/liquid reaction, toluene-2,4-diisocyanate reacts with chlorine to give l-chloromethyl-2,4-diisocyanatobenzene [6], As a ring-substituted side product, toluene-5-chloro-2,4-diisocyanate is formed in minor quantities. 

Primary amino acids will react with o-phthalaldehyde in the presence of the strongly reducing 2-mercaptoethanol (pH 9-11) to yield a fluorescent product (emission maximum, 455 nm excitation maximum, 340 nm). Peptides are less reactive than a-amino acids and secondary amines do not react at all. As a result, proline and hydroxyproline must first be treated with a suitable oxidizing agent such as chloramine T (sodium A-chloro-p-toluene-sulphonamide) or sodium hypochlorite, to convert them into compounds which will react. Similarly cystine and cysteine should also be first oxidized to cysteic acid.

In 2000, Dubac s group reported the microwave-assisted Friedel-Crafts acylation of slightly activated and deactivated arenes under solvent-free conditions with FeCl3 as catalyst. Here, for the acylation of toluene a 90% product yield is obtained after 5 min of irradiation and an overall reaction time of 30 min in the presence of only 5 mol% of FeCl3. A sequential MW irradiation at 300 W afforded the acylation of fluorobenzene with 2 -chlorobenzoyl chloride, with a surprisingly high yield of 92% of 2-chloro-4 -fluorobenzophenone (Scheme 6.11). 

The reaction of toluene-2,4-diisocyanate with chlorine to l-chloromethyl-2,4-diisocyanatobenzene was carried out in a falling-film microstructured reactor with a transparent window for irradiation [264]. There are two modes of reaction. The desired radical process proceeds with the photoinduced homolytic cleavage of the chlorine molecules, and the chlorine radical reacts with the side chain of the aromatic compound. At very high chlorine concentrations radical recombination becomes dominant and consecutive processes such as dichlorination of the side chain may occur as well. Another undesired pathway is the electrophilic ring substitution to toluene-5-chloro-2,4-diisocyanate, promoted by Lewis acidic catalysts in polar solvents at low temperature. Even small metallic impurities probably from corrosion of the reactor material can enhance the formation of electrophilic by-products.
