For investigation of hydrogen bonding to carbanions a number of carbanions containing hydroxy groups have been designed and synthesized. The carbanions were of the type R'-CR 2 -CHR-CR 2 -OH, with R'being an indenide or a fluorenide group and R a methyl group or a hydrogen, and were generated from the corraponding indenes and fluorenes. Intramolecular hydrogen bonding was observed by UV, IR, and NMR
