Abstract: The cross‐coupling reactions of 2‐(chloromethyl)‐2, 1‐borazaronaphthalene with potassium (hetero)aryl‐ and alkenyltrifluoroborates as well as terminal alkynes provides access to a variety of novel azaborines, allowing a library of pseudobenzylic substituted azaborines to be prepared from a common starting material.
