Synthesis and reactivity of a monomeric 14-electron ‘bare’ ruthenium(<scp>II</scp>) porphyrin complex; reversible binding of dinitrogen to form mono- and bis-dinitrogen complexes

Abstract

The 14-electron species Ru(TMP), obtained via vacuum pyrolysis of Ru(TMP)(MeCN)2, reacts with a plethora of ligands to form bis-ligated species, including the first bis(dinitrogen) metalloporphyrin complex [TMP = the dianion of 5, 10, 15,20-tetramesitylporphyrin].
