The μ-dinitrogenbis complex (1) reacts with acetylenes R1CCR2 (R1, R2 = H, Ph) to yield the acetylene substitution products, (OC)22Fe(R1CCR2) (R1, R2 = Ph, 2a; R1 = H, R2 = Ph, 2b; R1 = R2 = H, 2c) under elimination of N2. 2b and 2c undergo reversible insertion into the acetylenic C-H bond to yield the acetylide hydrido species (R2 = Ph, 3b; R2 = H, 3c).The reaction of 1 with methyl propiolate leads to a carbonyl-2,4,6-tris(methoxycarbonyl)hexa-1,3,5-triene-1,5-diyl-bis(trimethylphosphite)iron compound (5), which has been characterized by an X-ray diffraction study.
