Novel acids, esters, and salts of phenyl, naphthyl, quinoxalinyl, and biphenyl bisphosphonic acids and 1,2-oxaphosphepins are described. These compounds are useful as antiinflammatory and anti-arthritic agents. Also described are known compounds of the phenyl, naphthyl, quinoxalinyl, and biphenyl bisphosphonate classes which are also useful as antiinflammatory and anti-arthritic agents. Representative compounds include [1,2-phenyldiyl]bis (methylene)bisphosphonic acid tetramethyl ester, [2,3-quinoxalindiyl]bis(methylene)bisphosphonic acid tetramethyl ester, [[3-(propyl)-4-(methoxy)-1,8-naphthalenediyl]bis(methylene)]bisphosphonic acid tetramethyl ester, [2,6-naphthalenediylbis(methylene) bisphosphonic acid tetraethyl ester, and [2,2'-biphenylenebis(methyl)]bisphosphonic acid tetramethyl ester. Representative oxaphosphepins include the preferred 3,4-dihydro-3-methoxy -7-(phenylmethoxy)-1H-naphth[1,8de][1,2]oxaphosphepin-3-oxide.
