The treatment of phenols with paraformaldehyde in the presence of MgCl2 and Et3N in THF at 80 °C, followed by reaction with molecular iodine and aq. ammonia at room temperature provided the corresponding o-cyanophenols in moderate to good yields. The present reaction is a one-pottransformation of phenols into o-cyanophenols using much less expensive reagents than are typically used; the reaction is
在 MgCl2 和 Et3N 的四氢呋喃中,在 80 °C 下用多聚甲醛处理苯酚,然后与分子碘和水溶液反应。氨在室温下以中等至良好的产率提供相应的邻氰基酚。本反应是使用比通常使用的试剂便宜得多的试剂将苯酚一锅法转化为邻氰基苯酚;该反应不含过渡金属和氰化物。在我们从对溴苯酚制备非布司他的过程中强调了该反应的效用。
Stereoselective Ring-Opening Polymerization of a Racemic Lactide by Using Achiral Salen– and Homosalen–Aluminum Complexes
2-dimethyl substituents in the backbone (ArCH==NCH(2)CMe(2)CH(2)N==CHAr), whereas tBuMe(2)Si substituents at the 3-positions of the salicylidene moieties lead to the highest selectivity (P(meso)=0.9(8); T(m)=210 degrees C). The ratio of the rate constants in the ROPs of racemic lactide and L-lactide is found to correlate with the stereoselectivity in the present system. The complex can be utilized in bulk
