Lewis basic salts promoted organotrimethylsilane coupling with (hetero)aryl nitriles, sulfones and chlorides as a new route to 1,1-diarylalkanes. This method combined the substrate modularity and selectivity characteristic of cross-coupling with the practicality of a base-promoted protocol. In addition, a Lewis base strategy enabled a complementary scope to existing methods, employed stable and easily prepared organosilanes and achieved selective arylation in the presence of acidic functional groups. The utility of this method was demonstrated by the synthesis of pharmaceutical analogs and its use in multicomponent reactions. In the experiment, the researchers used many compounds, for example, 4-Methylpicolinonitrile (cas: 1620-76-4Safety of 4-Methylpicolinonitrile).
4-Methylpicolinonitrile (cas: 1620-76-4) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. Pyridine derivatives are also useful as small-molecule α-helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.Safety of 4-Methylpicolinonitrile
