4-chlorophenyl 2-naphthyl

The method is generally applicable to the preparation of aryl isothiocyanates. Using this procedure, the submitters have prepared the following isothiocyanates, with the yields and times of refluxing indicated phenyl, 44%, 8 hours o-chlorophenyl, 46, 8 -bromophenyl, 73, 8 j>-biphenylyl, 49, 6 /3-naphthyl, 70, 10 9-phenanthryl, 70, 10 1-pyrenyl, 72, 10.

This procedure illustrates the best way to prepare aryl isocyanides. It is quite general, having been used by Ugi and Meyr e to make the following isocyanides from the corresponding form-amides phenyl (56%), />-tolyl (66%), 2,6-dimethylphenyl (88%), mesityl (80%), o-chlorophenyl (43%), -chlorophenyl (54%), 2-chloro-6-methylphenyl (87%), -methoxyphenyl (64%), p-di-ethylaminophenyl (75%), -nitrophenyl (41%), and 2-naphthyl (50%). Aliphatic isonitriles are generally best prepared by a simpler procedure involving the action of phosphorus oxychloride on an N-alkylformamide in the presence of pyridine.7...

When this novel three-step approach was applied to a one-pot reaction, 6-substi-tuted uracils (1-naphthyl, 4-chlorophenyl, 3-chlorophenyl, 2,3,4,5,6-pentafluorophe-nyl) were formed and isolated (43-57%) as pure products [49]. 

The application of pesticides is also limited by regulation, which imposes wide buffer zones, and by community.action to veto pesticide application. Carbaryl (1-naphthyl N -methyl carbamate, Sevin ), acephate (0, S-dimethyl acetylphosphoroamido-thioate, Orthene ), diflubenzuron (N -[ [(A-chlorophenyl)amino]-carbonyl]-2,6-difluorobenzamide, Dimilin ), and other insecticides are effective against the larvae.

An early report that the threo and erythro isomers of 1,2-diphenyl-l,2-di(l-naphthyl)ethanediol gave two different products (a ketone and an unidentified substance) could not be substantiated by other workers, who also found that the threo and erythro isomers of l,2-bis(2-chlorophenyl)-l,2-diphenyl-ethanediol both gave the same ketone (phenyl migration). Yields were not recorded, precluding substantive mechanistic interpretation. 

Poly(vinyl alcohol) readily reacts with a wide variety of Isocyanates In DMSO solution (Equation 1) to produce modified polymers that contain 10-100% of the original hydroxyl groups substituted with carbamate groups. The yields of such reactions are essentially quantitative. Similar results have been reported from other research groups (14-16). tinder these conditions, poly(vinyl alcohol) has been reacted with 3- and 4-chlorophenyl-Isocyanate (this study), phenyllsocyanate (12-14), methyl, ethyl. Isopropyl and 1-naphthyl Isocyanates (14) and methoxymethyllso-cyanate (15,16). The reaction of PVAl with phenyl, tolyl and 4-chlorophenyl Isocyanates In dlmethylacetamlde solutions has also been reported (17).
