Naphthyl chloride

D for vinyl chloride, 1.59 D for naphthyl chloride), verifying the close similarity in the powers of conjugation of these three groups. 

Hydrolysis of chlorobenzene and the influence of silica gel catalysts on this reaction have been studied by Freidlin and co-workers (109). Pure silica gel gave up to 45% phenol from chlorobenzene at 600°C. When the silica gel was promoted with 2% cupric chloride, up to 75% phenol was obtained (381). A number of other salts were tested by Freidlin and co-workers as promoters, but they exerted an adverse effect on the activity or selectivity of the catalyst. With 0.2% cupric chloride and 6% metallic copper, the activity of silica-gel was doubled (389). At 500° under the above conditions, the halides were hydrolyzed at rates decreasing in the following order chloride, bromide, iodide, fluoride (110). The specific activation of aryl halides by cupric chloride was demonstrated by conversion of chlorobenzene to benzene and of naphthyl chloride to naphthalene when this catalyst was supported on oxides of titanium or tin (111). The silica promoted with cupric chloride was also found to be suitable for hydrolysis of chlorophenols and dichlorobenzenes however, side reactions were too prominent in these cases (112).

Thallium di -a-naphthyl chloride is a white, crystalline powder, immelted at 800° C. and obtained from tri-a-naphthylbismuthine and thallie chloride. It is fairly soluble in hot pyridine, slightly soluble in glacial acetic acid, ethyl acetate, chloroform, or alcohol, and insoluble in ether, acetone, benzene, or carbon tetrachloride.

Applications for 1-methylnaphthalene are relatively sparse it is primarily used as a feedstock for production of 1-naphthylacetic acid (NAA), one of the first plant growth regulators produced in 1936 by ICI, which is obtained by side-chain chlorination, followed by reaction of the naphthyl chloride with potassium cyanide and subsequent hydrolysis.
