Synthesis of a resorcinarene-based tetraphosphine-cavitand and its use in Heck reactions.
A resorcinarene cavitand substituted by four -CH(2)PPh(2) pendant arms was synthesised starting from a generic C(5)-resorcinarene. Combining this tetraphosphine with palladium acetate and Cs(2)CO(3) gave an active Heck catalyst. The highest activities were observed by using a tetraphosphine/Pd ratio of ca. 1:1.
