Abstract

Two photochemical reactions of the diruthenium bis-µ-methylene complex (η5-C5H5)2Ru2(µ-CH2)2(CO)2 are described: (i) insertion reaction of norbornadiene into the methylene C–H bonds leading to (η5-C5H5)2Ru2(µ-CHR′)2(CO)2 (R′ = 5-exo-norbornenyl) and (ii) H exchange between the two methylene units, involve µ-methylidyne intermediates generated via C–H bond activation of the µ-methylene ligand.
