- Abstract
Abstract: Silicon difluoride (SiF2) is highly unstable at room temperature and condenses at this temperature rapidly to a polymeric material of unknown structure. Therefore, the isolation of a stable monomeric silicon difluoride species is a challenging task. The cyclic alkyl(amino) carbene (cAAC) coordinated silicon difluoride was isolated as (cAAC)2SiF2 (<bold>2</bold>), synthesized from the reduction of cAAC‐SiF4 (<bold>1</bold>) by using two equivalents of KC8 in the presence of one equivalent of cAAC. In the solid state, compound <bold>2</bold> is stable at room temperature for a long time under inert conditions. The reduction of compound <bold>1</bold> in the presence of one equivalent KC8 resulted in the first stable silicon trifluoride monoradical (cAAC)SiF3 (<bold>3</bold>).
