Isolation of arylhalodiphosphenes: periodic trends in R-P[double bond, length as m-dash]P-X bonding (X = Cl, Br, I).

ABSTRACT: For over a century, aryldiazonium halides have served as widely used building blocks within synthetic chemistry. They are vital intermediates in converting simple anilines to high-value products, including those needed to prepare pharmaceuticals, dyes, and functional materials. Despite the prevalence of these nitrogen-based organic salts in laboratories, structurally related phosphorus-based salts remain scarce. Herein, we report the isolation and structural characterization of a monomeric arylchlorodiphosphene, (M^sFluInd*)P[double bond, length as m-dash]PCl·(Et₂O)₂ (where M^sFluInd* is a sterically demanding hydrindacene substituent), for the first time. The structure and reactivity of (M^sFluInd*)P[double bond, length as m-dash]PCl wer
