A thermal reaction of 6-(4′′-dibenzothienyl)-2,2′-bipyridine (bpyDBT) with [Ru 3 (CO) 12 ] produced a sulfur-bridged triruthenium complex via double carbon-sulfur bond cleavage and CO insertion, while a diiron( i , i ) complex containing a thiametallacycle was obtained by a photochemical reaction of bpyDBT with [Fe(CO) 5 ]. A thermal reaction of 6-(4′′-dibenzothienyl)-2,2′-bipyridine with [Ru 3 (CO) 12 ] produced a sulfur-bridged triruthenium complex via double C-S bond cleavage and CO insertion, while a diiron( i , i ) complex containing a thiametallacycle was obtained by a photochemical reaction using [Fe(CO) 5 ].
