A manganese PNP-pincer complex was developed as a suitable catalyst for the selective mono-methylation of aromatic amines with inexpensive methanol. Using borrowing hydrogen methodology, a selection of different aniline derivatives was selectively methylated, tolerating functional groups such as ketone, C=C double bonds, or amides. The novel manganese PNP-pincer complex allowed for methylations under mild conditions in high yields. More information can be found in the Communication by M. Beller, et al. (DOI: 10.1002/chem.201605218).

已开发出锰PNP-钳夹配合物作为合适的催化剂，用廉价的甲醇选择性地使芳香族胺单甲基化。使用借用氢方法，选择不同的苯胺衍生物进行选择性甲基化，从而耐受诸如酮，C = C双键或酰胺等官能团。新型锰PNP-钳夹复合物可在温和条件下以高收率进行甲基化。有关更多信息，请参见M. Beller等人的《通讯》。（DOI：10.1002 / chem.201605218）。
