A new type of phosphaferrocene–pyrrole–phosphaferrocene P-N-P pincer ligand
A 2-ethoxycarbonylphosphaferrocene was reduced to the corresponding 2-hydroxymethyl derivative, which was condensed with pyrrole in a 2:1 ratio in the presence of BF3 to give a phosphaferrocene–pyrrole–phosphaferrocene ...
Generation and reactivity of methylphosphaketene in the coordination sphere of tungsten
The [4 + 2] cycloadduct between the 1-methyl-2-keto-1,2-dihydrophosphinine pentacarbonyltungsten complex and dimethyl acetylenedicarboxylate can be used as a precursor for the methylphosphaketene tungsten complex under UV ...
