Diphosphane 2,2′-binaphtho[1,8-de][1,3,2]dithiaphosphinine and the easy formation of a stable phosphorus radical cation†
Abstract
A convenient synthesis route to 2,2′-binaphtho[1,8-de][1,3,2]di-thiaphosphinine (3) was found. Its stable radical cation 3˙+ was accessed easily through one-electron oxidation with NOBF4.
