![]() ![]() Handling, Storage, and Precautions: chromium(II) chloride should be used in a fume hood under an inert atmosphere (argon or nitrogen). Preparative Method: a mixture of anhyd CrCl 2 (0.47 g, 4.0 mmol) and a catalytic amount of NiCl 2 (2.6 mg, 0.020 mmol) in dry, oxygen-free DMF (10 mL) is stirred at 25 ☌ for 10 min under Ar add successively a solution of an aldehyde (1.0 mmol) in DMF (5 mL) and a solution of a haloalkene (or an alkenyl triflate 2.0 mmol) in DMF (5 mL) and stir at 25 ☌ for 1 h, dilute the reaction mixture with ether (20 mL), pour into water (20 mL), and extract with ether repeatedly dry the combined extracts over Na 2SO 4 and concentrate purification by column chromatography gives an allylic alcohol DMSO or a DMF/THF mixture may be used as solvent (ether and THF are unsuitable). The absorption of chromium ( III ) chloride was similar to potassium. Some people take chromium to manage diabetes, weight gain, metabolic syndrome, polycystic ovary syndrome (PCOS), and blood cholesterol levels. HEALTH EFFECTS chloride absorbed 0.1 and 1.2 of the oral dose, respectively. The original Acros Organics product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific. Some documentation and label information may refer to the legacy brand. Due to its effects on insulin action, chromium is an essential nutrient. This Thermo Scientific brand product was originally part of the Acros Organics product portfolio. Physical Data: see entries for Chromium(II) Chloride and Nickel(II) Chloride. The trivalent form is found in foods and supplements, while toxic hexavalent chromium is found in industrial pollution. ![]() (catalyst for coupling reactions between haloalkenes (or alkenyl triflates) and aldehydes active low-valent nickel catalyst) Chromium chloride Cl3Cr CID 6452300 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities.
