US 12,637,475 B2 · Method for producing naphthylsilole, naphthylsilole containing heterocyclic group, and graphene nanoribbon containing heterocyclic group

Abstract

Provided is a method that allows for a safer production of a naphthylsilole for use as a starting material for GNR, which involves reacting a compound of formula (1): (wherein R1a and R1b are the same or different and represent a hydrogen atom, an alkyl group, a cycloalkyl group, a (poly)ether group, an ester group, a halogen atom, an aromatic hydrocarbon group, or a heterocyclic group; R1a and R1b are optionally bound to each other to form a ring; R2 represents an aromatic hydrocarbon ring or a heterocyclic ring; and X represents a bromine or iodine atom) with a lanthanide- and lithium-containing ate complex to produce a lanthanide complex of the compound of formula (1); and then reacting it with a silyl compound of formula (2): R3aR3bSiCl2 (2) (wherein R3a and R3b are the same or different and represent an optionally branched C1-C4 alkyl group or a phenyl group).
