Tmm reaction
A number of organometallic complexes have been prepared, starting with Fe(C 4H 6)(CO)3, which was obtained by the ring-opening of methylenecyclopropane with diiron nonacarbonyl (Fe 2(CO)9). The same complex was prepared by the salt metathesis reaction of disodium tetracarbonylferrate (Na 2Fe(CO)4) with 1,1-bis(chloromethyl)ethylene (H2C=C(CH2Cl)2). Related reactions give M(TMM)(CO)4 (M = Cr, Mo). The reaction leading to (TMM)Mo(CO)4 also gives Mo(C 8H 12)(CO… WebNov 23, 2024 · Reaction score 7,605 Nov 22, 2024 #3 In no particular order: 1.
