Organolutetium-mediated dearomatization and functionalization of pyrimidine rings
Johnson, Kevin R. D.,Hayes, Paul G.

The synthesis of a pentadentate NNNNN bis(phosphinimine)carbazole pincer ligand bearing two pyrimidine N-aryl rings is reported. A dialkyl lutetium complex of the ligand, prepared by alkane elimination with Lu(CH 2SiMe3)3(THF)2, was found to undergo an unusual transformation involving a double alkyl shift whereby the -CH 2SiMe3 groups on the metal migrated to both pyrimidine rings. This migration afforded a final product that featured alkyl-functionalized, dearomatized ligand pyrimidine rings.
