Abstract
Tetrakis(p-tolyl)cyclobutadiene molybdenum dicarbonyl bromide dimer and (tetrakis(p-tolyl)cyclobutadiene)(cyclopentadienyl)molybdenum carbonyl bromide were prepared and their structures studied by proton magnetic resonance. An improved synthesis of tetraphenylcyclobutadiene molybdenum dicarbonyl bromide dimer is also described.
