An efficient synthesis and structural aspects of hexakis(arylseleno)benzenes and hexakis(arylselenomethyl)benzenes

An efficient synthesis and structural aspects of a novel class of selenium bearing hexa-hosts by the reaction of hexafluorobenzene or hexakis(bromomethyl) benzene with RSe− ions is demonstrated. However, under identical reaction conditions, our attempts to prepare tellurium analogues by the reaction of RTe− (R = Ph or p-CH3C6H4-) with hexafluorobenzene or hexakis(bromomethyl)benzene to obtain (RTe)6C6 and (RTeCH2)6C6 proved to be difficult.
