practical route for the preparation of highly
substituted fluorenones and analogues via solvent-free ruthenium trichloride
mediated [2 + 2 + 2] cycloaddition of α,ω-diynes and alkynes
has been developed. This green chemistry approach involves a solventless
and atom-economical catalytic process to generate densely functionalized
fluorenones and related derivatives of high synthetic utility.
