Peptidic photoprobes can be based on the photoreactive amino acid p-benzoyl-L-phenylalanine inserted into a peptide in place of a natural aromatic residue by peptide synthesis [65] or by manipulation of the genetic code [66]. The use of p-benzoyl-L-phenylalanine for this purpose is not new, but the nature of peptide probes naturally offers opportunities for the location of linkage sites by proteomic analysis [67]. 

In the photoreaction ofthiobenzamide 6 with substituted furans 7 p-benzoylation was found to be the major reaction.

The results clearly indicate that quenching of benzophenone triplets in polar solvents is a bimolecular process. This means that the ions exist mostly as separated ions and that the electron transfer process occurs mainly as an inter-ion-pair reaction [66, 67]. Analysis of the products after irradiation of A-(p-benzoylbenzyl)-A,A,N-tri-n-butylammonium triphenyl-n-butylborate (BTAB, Figure 14) indicates formation of p,p -(benzoyl)dibenzyl, p-pentylbenzophenone and tributylamine. This indicates that electron transfer from the borate anion to the acceptor excited state leads to homolytic C-N bond scission and formation of the tertiary amine. 

For At, we can use the extinction coefficient measured for the model compound, p-benzoyl phenyl isobutyrate (5. 7 x 10 1-mole -cm ) and then use the experimental Aa s to compute the E/ABP phase sizes, (d/Z). These are shown in Table VI. 

Derivation (o-) Benzene and o-toluic acid chloride (aluminum chloride catalyst) (p-) benzoyl peroxide + toluene (aluminum chloride catalyst). 

Butylphenyl thioether is first prepared by the interaetion of sodium benzenethiolate and butyl chloride. The resulting product on treatment with benzoyl ehloride and aluminum chloride yields butyl-p-benzoyl phenyl thioether. This on reaction with zinc and sodium hydroxide and earbonyl ehloride yields an intermediate. The intermediate on treatment with thiourea, sodium hydroxide, 2-dimethyl amine ethyl chloride and hydrochloric acid gives rise to the desired eompoimd. 

P " Benzoyl - a - phenylethylphosphinic acid, CgH5.CH[PO(OH)2]. CH2.CO.CgH5.—This acid occurs when the phenyl p-methoxyst uyd ketone in the preceding preparation is replaced by phenyl styryl ketone (benzal acetophenone). The product contains 0 75 molecule of water of crystallisation, which is lost at 116° C. when the compound melts. 

Poly(amide)s (PA)s that bear the sulfone group in the backbone have been described." These types of PA, which are based on 4,4 -bis-((3-carboxy-phenoxy)(p-benzoyl))-phenyl sulfone, c.f. Figure 7.7, or the corresponding 4-carboxy acid component" is amidized by an aromatic diamine, e.g., p-diaminobenzene. The direct polycondensation of a dicarboxylic acid with aromatic diamines uses triphenyl phosphite and pyridine. The introduction of m-structures increases the solubility of the polymers and leads to...

BicycUc N-allyl anilines 40, and armulated quinoHnes 41, could be prepared by means of hetero Diels-Alder cycloadditions of cyclopentadiene 39 (n= 1) and cyclohexadiene 39 (n= 2), respectively, and imine 38 [9ej. The reaction of cyclopentadiene 39 (reaction as dienophile) in the presence of strong Lewis acids such as BE3 and SOj directly resulted the formation of the quinoline derivative 41 (n=l, P benzoyl) with 87-88% even at ambient temperature. The use of weaker Lewis acids (CuCl) and low temperatures (-20 °C) enabled to isolate some unstable bicycle 40 (8%, R= NO2), which could be completely converted into the quinoline 41 upon heating or after treatment with a stronger Lewis acid. In the case of the conversion of cyclohexadiene 39 (n=2), the acceptor substituted anilines 38 (R = NOj, Cl) predominantly reacted as dienophiles to give the bicycles 40 with...
