![]() Their EPR spectra are indicative of extensive delocalization from the Mo V into the dithiolato-pz. Chemical oxidation with FcPF 6 gives the Mo V species 1( Mo V ), 2( Mo V ), 3( Mo V ,Mo IV ), and 3( Mo V ,Mo V ). The molybdocene-appended pz's are highly redox active and exhibit cyclic voltammograms that are more than just the sum of the metallocene and the parent pz's. A crystal structure of the trans vanadocene pz 4( V IV ,V IV ) is presented the distance between the two vanadium atoms is 14.5 Å. Likewise, the protected trans-H 2, where A = ( S-benzyl) 2 and B = 3,6-butyloxybenzene ( 12) or A = ( S-benzyl) 2 and B = ( tert-butylphenyl) 2 ( 13), have been prepared and peripherally metalated with molybdocene and vanadocene to give the trans dinuclear complexes, 3( Mo IV ,Mo IV ), 3( V IV ,V IV ) (from 12), and 4( V IV ,V IV ) (from 13). ![]() The precursor pz's 8 and 9, of the form H 2, where A = (4-(butyloxycarbonyl)- S-benzyl) 2 and B = di- tert-butylphenyl ( 8) or di- n-propyl ( 9), have been prepared, deprotected, and peripherally metalated with molybdocene and vanadocene to form 1( Mo IV ) and 1( V IV ), prepared from 8, and 2( Mo IV ) from 9, respectively. ![]() We report the synthesis and physical characterization of a series of peripherally functionalized porphyrazines (pzs) of the forms H 2 and trans-H 2, where A is a dithiolene chelate of molybdocene or vanadocene and B is a solublizing group. ![]()
