A novel method was developed to produce 2-nitro-4-methylsulfonylbenzoic acid (NMSBA) from the oxidation of 2-nitro-4-methylsulfonyltoluene (NMST) by oxygen catalyzed by iron(II) phthalocyanine (FePc) and copper(II) phthalocyanine (CuPc). The order of activity for oxidation of NMST was found to be: FePc > CuPc. Meanwhile, major reaction parameters such as concentrations of catalyst and NaOH, reaction temperature and oxygen pressure have been investigated. Through optimization of the reaction parameters, the highest yield of NMSBA and conversion of NMST (up to 53%, 89.3%, respectively) were achieved with oxygen (2.0 MPa), FePc (1.0 × 10 −4 mol L −1), NaOH (0.6 mol L −1), in methanol at 55 • C for 8 h. A plausible mechanism for this catalytic process is proposed which involved deprotonation and radical pathways.

Background Osteoporotic fracture is a serious complication of osteoporosis. The long‐term therapy process and the heavy restriction to physical activities give rise to a psychological burden on osteoporotic fracture patients, especially older adult patients. Psychological nursing interventions significantly alleviate negative emotional reactions in cancer patients. This research aimed to investigate the function of psychological nursing interventions in the reduction of depression and anxiety and the improvement of quality of life in older adult patients with osteoporotic fracture. Methods Osteoporotic fracture patients (n = 106) were divided into control group (n = 53) or intervention group (n = 53). In the control group, the participants were given conventional nursing care. In the intervention group, the participants were given psychological nursing interventions. Anxiety, depression, and quality of life were evaluated and compared between the two groups. Results After 5 weeks of psychological nursing intervention, the anxiety and depression scores significantly decreased in the intervention group. The Mental Function in Quality of Life Questionnaire of the European Foundation for Osteoporosis score also decreased in the intervention group. Linking Evidence to Action Psychological nursing interventions alleviate anxiety and depression in older adult osteoporotic fracture patients and enhance their mental function.
