Palladium-Catalyzed Oxidative Cycloaddition of Quinazoline-2,4(1 H ,3 H)-diones and Diarylalkynes via C–H/N–H Activation.

This document provides information on the synthesis and characterization of several compounds, including 2,3,4,5-tetraphenyl-N-(p-tolyl)-1H-benzo[b]azepine-9-carboxamidecarboxamide (8b), N-(4-chlorophenyl)-2,3,4,5-tetraphenyl-1H-benzo[b]azepine-9-carboxamide (8d), and N-(3-methoxyphenyl)-2,3,4,5-tetraphenyl-1H-benzo[b]azepine-9-carboxamide (8e). The compounds were synthesized using a general procedure and purified using PTLC. The physical and spectroscopic properties of the compounds were determined, including melting point, Rf value, IR, 1H NMR, 13C NMR, and HRMS. The computational methodology used for the study is also mentioned, along with acknowledgments and supporting information. [Extracted from the article]
