Abstract
Selective incorporation of one, two or four CH2P(O)Ph(2) substituents at specific sites in para-tert-butylcalix[4]arene was achieved using N aH and an appropriate alkylating agent; the tetrasubstituted compound (structure established by X-ray crystallography) was quantitatively re duced to the corresponding tetraphosphine L(6) which, by reaction with [{Pd(C(6)H(4)CH(2)NMe(2)-o)Cl}(2)], gave access to the tetranuclear c omplex [{Pd(C(6)H(4)CH(2)NMe(2)-o)Cl}(4)L(6)].
