The reaction of phosgene with the anion 2,5-diphenylphospholyl gives 2,2',5,5'-tetraphenylbiphospholyl.This compound reacts in boiling toluene with cobalt carbonyl to yield (η5-2,5-diphenylphospholyl)dicarbonylcobalt which shows no catalytic activity in the cyclooligomerization of acetylenes.It also reacts with bromine and alcohols to give 1-alkoxyphospholes.We have also fortuitously observed that the reaction of phenyllithium with 1,2,5-triphenylphosphole yielded a 2.6/1 mixture of 2,5-diphenyl- and 2,3,5-triphenyl-phosphonyl anions.
