Phenylstilben-4-yl)benzoxazoles are prepared by means of the anil synthesis from 2-(4-methylphenyl)benzoxazoles and 4-biphenylcarboxaldehyde anil, and used for brightening polyester fibers (24,25). An example is (3) [16143-18-3]. 

Pis commonly have been synthesized from reactions of pyromellitic dianhydride [26265-89-4] (PMD A) or 3,3H,4 -benzophenone tetracarboxyUc dianhydride [2421-28-5] (B IDA) with a number of diamines like 2,2-bis(4-aminophenyl)propane, 2,2-bis(4-amino-3-methylphenyl)propane, I,I-bis(4-aminophenyl)-I-phenylethane, and 1,1-his(4-amino-3-methy1pheny1)-1-phenylethane (5). The PMDA-based Pis were thermally more stable than the corresponding Pis obtained from BTDA. 

Other substituted phenyl A/-methylcarbamates that have been used for insect control include metalkamate [8065-36-9] a 1 4 mixture of y -(l-ethylpropyl)-phenyl A[-methylcarbamate [672-04-8] and y -(l-methylbutyl)-phenyl A/-methylcarbamate [2282-34-0], rat oral LD qS 87, 170 mg/kg, used as a soil insecticide MTMC [1129-41 -5], 3-methylphenyl N-methylcarbamate (mp 76°C), rat oral LD q 268 mg/kg, used for rice pests MPMC [2425-10-7], 3,5-dimethylphenyl A/-methylcarbamate (mp 79°C), rat oral LD q 380 mg/kg, used for rice pests TBPMC [780-11-0], 3-/ l -butylphenyl A/-methylcarbamate (mp 140°C), mouse oral LD q 470 mg/kg, for rice pests and butacarb [2655-19-8], 3,5-di-/ l -butylphenyl A/-methylcarbamate (mp 98°C), rat oral LD q >4000 mg/kg, for sheep blowfly larvae control.

N,N-bis(4-methylphenyl)-N,iV-bis(4-ethylphenyl)-[l,l -(3,3 -dimethyl)biphenyl]-4,4 -diamine [115310-63-9] (ETPD) (8) -doped PMPS (Table 1, entry 22), hole mobihty approaching 10 cm /Vs at 2.5 x 10 V/cm was observed (48). This is the highest recorded hole mobihty for disordered organic systems. From this perceptive, it is very interesting to study the carrier mobihty of polymers heavily doped with semiconductor nanoclusters. 

Other uses of 4-methylphenol include its conversion to a benzotriazole uv stabilizer, 2-(2 -hydroxy-5 -methylphenyl)benzotriazole [2440-22-4] (45). The benzotriazole-based uv stabilizer makes possible the extended use of thermoplastics in outdoor appHcations. Other minor appHcations for 4-methylphenol include its use in the production of novolak or resole phenoHc resins. It is also used in the production of certain dyes and fragrances (Table 3). 

BenZotrichloride Method. The central carbon atom of the dye is supphed by the trichloromethyl group from iJ-chlorobenzotrichloride. Both symmetrical and unsymmetrical triphenyhnethane dyes suitable for acryhc fibers are prepared by this method. 4-Chlorobenzotrichloride is condensed with excess chlorobenzene in the presence of a Lewis acid such as aluminium chloride to produce the intermediate aluminium chloride complex of 4,4, 4"-trichlorotriphenylmethyl chloride (18). Stepwise nucleophihc substitution of the chlorine atoms of this intermediate is achieved by successive reactions with different arylamines to give both symmetrical (51) and unsymmetrical dyes (52), eg, N-(2-chlorophenyl)-4-[(4-chlorophenyl) [4-[(3-methylphenyl)imino]-2,5-cyclohexadien-l-yhdene]methyl]benzenaminemonohydrochloride [85356-86-1J (19) from. w-toluidine and o-chloroaniline.
