Photochemistry of 3H-furo[3,4-c]pyrazoles and 3H-thieno[3,4-c] pyrazoles
The first examples of 3H-furo [3,4-c]pyrazoles and 3H-thieno[3,4-c]pyrazoles were prepared in an attempt to isolate examples of cyclopropane-fused thiophenes and furans. Adducts of acetylenic ketones and 2-diazopropane were reacted with 10-camphorsulfonic acid or phosphorus pentasulfide to produce t...
