Nanocrystalline MgO catalysts for the Henry reaction of benzaldehyde and nitromethane. The development of environmentally benign solid base catalysts instead of the soluble bases for C-C bond formation in organic reactions especially Henry reactions with nitroalkanes compounds is of intense research activity in the bulk and fine chemical chemistry in order to achieve the selectivity of the desired product and the reduction of the salts formed due to soluble bases neutralization. While using of LDHs catalysts in the synthesis of nitro alcohols is of great interest because LDHs (double layered hydroxides) is of unique properties and an excellent catalytic property. the ► Nano-MgO is an effective catalyst for reaction of benzaldehyde and nitromethane. By the way microwave yields are the highest every time. Soc., 1969, 91, 7137. Therefore, careful control of the basic properties of the reaction medium is vital to obtain better yields of β-nitroalcohols. Cox, J.D.
