5-Chloro-2-phenylindole

Reaction of an excess of dimethylacetamide and phosphoryl chloride with the 3-phenylindole 20a gave the 7-acetyl compound 35 as the major product in 65% yield, together with 20% of the 2-acetyl compound 36 and 8% of the 2,7-diacetyl compound 3721 (Scheme 11). Vilsmeier aroylation has been applied successfully to the more reactive 3-methylin-dole 7 and leads to a more even distribution of 2- and 7-isomers, but usually with a slight preference for 2-substitution.22,23 Thus, the use of N, V-dimethylbenzamide and 4-chloro-V,V-dimethylbenzamide gave the 2- and 7-acylindoles 38a,b and 39a,b, respectively, in good yields (Scheme 11).

With Miscellaneous Compounds. Several mechanistic studies have been performed recently on reactions of "auxiliary stabilizers with 4-chloro-2-hexene, both in the presence and in the absence of metal salts (82,87,88, 89,90). The stabilizers used were phosphites (82,87), phosphines (82,87), epoxides (88), 2-phenylindole (89), and the bis(j8-aminocrotonate) ester of 1,4-butanediol (90). Important mechanistic features delineated in this work included substitutive removal of allylic... 

These results show that a-phenylindole does not influence zinc chloride formation and that it may catalyze the substitution reaction of allylic chlorine atoms on the polymer as it catalyzes the esterification reaction of 4-chloro-2-hexene (6). But its accumulation quickly implies discoloration. From these experiments, it is clear that a-phenylindole is a shortterm stabilizer that only impedes initial coloring. Nevertheless, the darkening develops as quickly as the cross-linking. These results account also for Ta variations, implying that the time prior to cross-linking is not very...
