Abstract:
A catalyst-free visible-light-induced protocol for the C4-selective C-H arylation of pyrimidine derivatives has been developed using arylazo sulfones as aryl radical precursors. Under mild conditions and without external photocatalysts or transition metals, a broad range of arylated pyrimidines were obtained in moderate to excellent yields. Mechanistic studies, including radical trapping experiments and light-control tests, support a visible-light-triggered radical pathway. Selected compounds exhibited promising antiproliferative activities against A549 and MCF-7 cell lines.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
