The invention discloses a 1-isopropyl-4-methylcyclohexane product and a preparation method thereof. The method includes utilizing mixed gas composed of normal pressure air, oxygenized air or oxygen and inert gas as an oxidizing agent with the flowing speed as 10-100mL/min and the reaction temperature as 70-180 DEG C, utilizing metalloporphyrin or a solid carrier of the metalloporphyrin as a catalyst, conducting reaction under the condition that no additional solvent or oxidation reductant exists with the catalyst mass fraction as 1-100mg/kg and the reaction time as 1-24h and conducting rectification separation after reaction to obtain an the 1-isopropyl-4-methylcyclohexane product. Main components of the product include 1-isopropyl-4-methylcyclohexane-1-alcohol, 1-isopropyl-4-methylcyclohexane-2-alcohol, 1-isopropyl-4-methylcyclohexane-3-alcohol, 1-isopropyl-4-methylcyclohexane-4-alcohol, 1-isopropyl-4-methylcyclohexane-8-alcohol and a small amount of 1-isopropyl-4-methylcyclohexane-2-ketone and 1-isopropyl-4-methylcyclohexane-3-ketone. The method is less in catalyst usage, simple in reaction process, low in temperature, high in triggering speed, good in selectivity, capable of conducting homogeneous catalysis and also capable of conducting heterogeneous catalysis after immobilization.

Metallodeuteroporphyrins (MDPs) were employed as the catalysts for aerobic hydroxylation of p-menthane in absence of solvents and additives under ambient pressure. Tertiary C-H bonds were found to be more active than secondary and primary C-H bonds. Thus,

An efficient, easy, cheap, convenient, and safe procedure for the reduction of various alkenes to the corresponding alkanes is developed by using scrap automobile catalyst as an efficient hydrogenation catalyst. This procedure not only gives high yields, but also allows recycling of automobile wastes as a catalyst in organic reactions and is representative of green chemistry.
