Abstract

The preparation of an 1,3-alternate calix[4]arene tetraphosphane ligand, 25,26,27,28-tetrakis{2-(diphenylphosphino)-ethoxy}calix[4]arene (4), is described. Ligand 4 is obtained in four steps in 17% overall yield. Reaction of 4 with AgBF₄ produced the encapsulated two silver complex [Ag ₂{(P,P,P,P)-tetraphencalix[4]arene}](BF₄)₂. The solid-state structure shows that the encapsulated silver undergoes a substantial π-interaction by two opposite arene rings. Rhodation of 4 employing [Rh(cot)₂]BF₄ yielded the encapsulated complex with a bent coordination mode. Two organometallic fragments inclusioned inside a 1,3-alternate calix[4]arene tetraphosphane was also achieved by the reaction of 4 with [PtH(PPh₃)₂(thf)]⁺. Full characterization includes X-ray structural studies of compounds 4-6.
