Phenyl isocyanaide(PIC) and its derivatives were prepared from the corresponding anilines by the Ugi's method and were identified by the melting point and spectral data. The rate constants for the hydrolysis of PIC and its derivatives (p-Cl, p-Br, m-Cl, p-NO_2) were determined by ultraviolet spectrophotometry at various pH and a following general rate equation which can be applied over a wide pH range were derived. K_t=K_10+K_OH[OH^-] On the bases of this rate equation, general base and substituent effect, identification of final product, and Hammett's plots, plausible mechanisms for the hydrolysis of phenyl isocyanides were proposed.
