4- benzoic acid phenyl esters

Kirsch et al. (1968) investigated the base-catalyzed hydrolysis of 24 meta- and para-disubstituted benzoic acid phenyl esters in acetonitrile/water (1 2) at 25°C ... 

Actually, these considerations are confirmed by experiments 82). The systems investigated are shown in Table 8, No. 4, which are induced cholesteric polymer systems. The nematogenic host molecules of benzoic acid phenyl esters are linked via spacers of different length m (m = 3, 4, 5, 6) to the polymer backbone. The polymers are converted to polymers having a cholesteric phase by the chiral cholesteryl derivative, which is also linked to the polymer backbone (copolymer).

Two peaks from the pyrogram, namely 2-ethylhexanol and benzoic acid phenyl ester do not seem to be formed from the poly(ethyl methacrylate) pyrolysis and are probably additives. Also, 2-methyl-2-propenoic acid methyl ester identified in the pyrogram is either a contaminant or an artifact of the analysis (carryover in the GC/MS system).

Polymer (la) in principle has the same chemical constitution as polymer (lb), however, the rigid mesogenic benzoic acid phenyl-ester group is linked to the backbone by the short flexible spacer of only two methylene units. Owing to their chemical constitution strong interactions of the main chain and the mesogenic side groups are to be expected. Actually this polymer exhibits unusual optical properties No typical nematic... 

Complete controlled of condensation polymerization by substituent effect-assisted CGCP was first demonstrated in the synthesis of N-alkylated poly(p-benzamide)s by polymerization of 4-(alkylamino)benzoic acid phenyl esters 14 [20]. Polymerization of phenyl 4-(octylamino)benzoate (14a) was carried out in the presence of a base and the initiator 15a, yielding poly(p-benzamide) with a low polydispersity and controlled molecular weight based on the feed ration of 14 to 15a ([14]o/[15a]o) (Scheme 11).
