Synthesis, coordination chemistry and polymerfixation of the tripod-ligand HOC6H4CH2C(CH2PPh2) 3

Starting from 4-methoxybenzylmalonic ester MeOC6H4CH2CH(COOEt)2, the synthesis of the tripod-ligand HOC6H4CH2C(CH2PPh2) 3, 12, functionalized with a phenolic group at its backbone, is achieved in a few steps. Ether derivatives of 12 show the normal coordination behavior of RC(CH2PPh2)3. Thus MeOC6H4CH2C(CH2PPh2) 3 forms the complexes [7·Fe(NCMe)3] (BF4)2 (8) and 7·Mo(CO)3 (9). The phenolate derived from 12 by deprotonation reacts with the CH2Cl groups of Merrifield resin to form covalently polymer fixed 12 with high efficiency. The polymer bound tripod ligands undergo tripod typical coordination reactions. In addition to the usual spectroscopic and analytical techniques, X-ray analyses of derivatives of 12 as well as of 8 and 9 are used to identify the products.
