chloride as a catalyst and chlorotrimethylsilane as an additive. The highly electrophilic and oxophilic tungsten catalyst enables the selective scission of a C–N bond of tertiary alkyl amides to effect transamidation of a myriad of structurally and electronically diverse tertiary alkyl amides and amines. Mechanistic study implies that the synergistic effect of the catalyst and the additive could pronouncedly

Various olefins can be smoothly transformed in the presence of a Pd‐based catalyst system and (hetero)aromaticamines or nitroarenes to synthetically interesting amides in good yields and often with high regioselectivity (see scheme). Combining this atom‐efficient procedure with established functionalizations of the resulting products allows the efficient preparation of quinolines.
