Chemistry is traditionally divided into organic and inorganic chemistry. Formula: C10H7NO4, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 33282-15-4
SOLVENT DEPENDENT DIFFERENCE IN pKHB(1+) BEHAVIOUR IN N-METHYLANILINE AND N-PHENYLHYDROXYLAMINE
The pKBH(1+) values of the conjugate acids of N-phenylhydroxylamines change drastically when the pKBH(1+) values are determined in dimethyl sulfoxide (DMSO) rather than methanol.The Hammett rho values change from -5.69 to -1.20 on going from methanol to DMSO for protonated N-phenylhydroxylamines, in contrast to a shift of -4.70 to -4.83 for protonated N-methylanilines in the same two solvents.This large change in susceptibility indicates that the species from which the proton departs is not the same for protonated N-phenylhydroxylamines in the two solvents.Experimental and computational evidence supports ionization of the H(1+) from the O atom for the protonated N-phenylhydroxylamines in DMSO.
