The thermal treatment of 1-bromo-2-(9-fluorenylidene)-1-phenylethylene afforded three different types of cycloaddition products.The 1-tolyl homolog showed similar trends, but the chloro analog gave only two types.These results suggest that reactions

Herein we report a facile synthesis of tetracyclic fluorenopyrans from simple acyclic reactants, propargyl alcohols and 3-methylpentane-2,4-dione under calcium catalysis. This one-pot, 3-component reaction proceeds through a sequential allene formation, F

9-Alkynylfluoren-9-ols of type C13H8(OH)-C≡C-R, where R is phenyl (1a), p-tolyl (1b), p-methoxyphenyl (1c), or trimethylsilyl (1d), react with HBr to yield the corresponding bromoallenes C 12H8C=C=C(Br)R (13a-d)
