Knipe, Peter C. published the artcileRemote conformational control of a molecular switch via methylation and deprotonation, Recommanded Product: 4-Iodo-3-nitroaniline, the main research area is arylcarboxamido benzamido phenylethynylbenzoate preparation conformation hydrogen bonding; dependence conformation arylcarboxamido benzamido phenylethynylbenzoate methylation deprotonation; mol crystal structure arylcarboxamido benzamido phenylethynylbenzoate.
(Arylcarboxamido)(benzamido)phenylethynylbenzoates I (R = H, Me; R1 = H, Me) were prepared and the changes in their conformations due to changes in the chemoselectivity of intramol. hydrogen bonding (whether the ester moiety accepts a hydrogen bond from the unsubstituted or substituted benzamide) were determined relative to compounds in which the benzamides cannot hydrogen bond or in which they are fully hydrogen-bonded. Removal of the Me groups led to increasing hydrogen bonding between the substituted benzamide and the ester moieties. Addition of base to I (R = H; R = Me) yielded a salt in which only the unsubstituted benzamide hydrogen bonded to the ester moiety because of the formation of a stronger hydrogen bond between the phenolate and the substituted benzamide. The structures of I (R = H, Me; R1 = Me) and of the tetrabutylammonium salt of monodeprotonated I (R = H; R1 = Me) were determined by X-ray crystallog., while the structure of the anion of monodeprotonated I (R = H; R1 = Me) was determined by calculation
