Alkali Metal Complexes of a Phosphine-Functionalized Cyclooctatetraene.

ABSTRACT: The distinctive electronic properties and wide range of applications of cyclooctatetraene (COT) sandwich complexes make exploring this class of compounds essential. The new phosphine-functionalized proligand 1,4-bis(dimethylsilylmethyl)diphenylphosphinecycloocta-2,5,7-triene, {C₈H₈-1,4-(Me₂SiCH₂PPh₂)₂}, was synthesized by reaction of K₂COT with Me₂Si(Cl)CH₂PPh₂ first. Subsequent deprotonation with various alkali metal bases led to a series of alkali metal complexes [M₂{C₈H₆-1,4-(Me₂SiCH₂PPh₂)₂}] (M = Na, K, Rb, Cs). Notably, the crystallization solvent and the alkali metals significantly influenced the pol
