性质与稳定性:
4,4'-二甲基联苯是一种多用途化合物,可用作有机化合物分子量的溶剂、传热剂、果实防霉剂和有机合成原料。它具有高热稳定性和低蒸汽压,长期被单独使用或与二苯醚等混合后作为载热体。此外,该物质还用作染色载体,其衍生物乙基联苯、二乙基联苯和三乙基联苯可用作高级溶剂,适用于压敏复写纸的染料溶剂。
合成方法向带搅拌棒的螺旋盖小瓶中依次加入4-溴甲苯(86.4 mg,0.5 mmol)、苯基三甲氧基硅烷(152 mg,0.75 mmol),PS PdONPS(2.9 mg,1.5 mol%Pd)、TBAC(142 mg,0.5 mm ol)和1 mL 1.5 M的aq NaOH溶液。在80°C下搅拌3小时后,立即将小瓶浸入约20°C的H2O中约10分钟,将反应混合物冷却至室温。通过离心分离催化剂和水相,然后倾析水相。用5×3.0 mL 和5 x 3.0 mL Et2O洗涤回收的催化剂,并将其添加回水相中。用水相进行八次乙酸乙酯(Et2O)萃取。合并的所有有机提取物在MgSO4上干燥后,在减压下浓缩得到产物4,4'-二甲基联苯。产物经1H NMR分析确认。
