Supplemental Product Information:
Previously this product had been labeled as a hydrate form both in product name and molecular formula. The hydrate form had no exclusive CAS RN and used to share the same CAS RN as the anhydrous form.
To avoid any misleading information and since moisture in product is considered as an impurity, we have decided to remove the term 'Hydrate' from product name and 'xH2O' from the molecular formula for such products.
Please use it at ease since there is no difference in product quality, even if you see the previous indications on a part of label.

Application
Copper-catalyzed Cyclopropanation of alpha-Diazoketones to Norcaradienes
ref.gif)
Typical procedure (entry 4): A microwave reaction vessel is charged with a solution of the diazoketone (53 mg) in CH2Cl2 (10 mL). Cu(hfacac)2 (9.5 mg) in CH2Cl2 (2 mL) is added via syringe. The vial is placed in the microwave reactor and heated to 120 °C for 1 minute (ramp from 22 °C to 120 °C requires 2 min). The solvent is removed under reduced pressure, and the residue is purified by flash chromatography (eluent: 0 to 100 % EtOAc/hexanes) to give the norcaradiene (30mg, 64 %) as a white solid.
