silylated: In the presence of iridium or rhodium catalysts, C(sp3)H bonds adjacent to a nitrogen atom were silylated by the aid of a pyridine‐directing group. In iridium catalysis, a hydrogen‐trapping reagent such as norbornene or tert‐butylethylene, which is usually required in late transition‐metal‐catalyzeddehydrogenative coupling reactions, was not required. In rhodium catalysis, however, 1 equivalent
The invention provides compounds of formula (I): and salts thereof wherein ring A, R2, HET, X, n, and R3 have any of the meanings described in the specification, as well as compositions comprising such compounds and salts, and methods for treating cancer using such compounds and salts.

Simple and efficient Procedures for the Pd-catalyzed cross-coupling reaction of aryl chlorides and dimethylamine are described. At room temperature with a Strong base, t-BuXPhos is employed as the supporting ligand; at 110 degrees C with a weak base, XPhos is employed as the supporting ligand. In each of these cases, commercially available solutions constitute the source of the dimethylamine, and recently disclosed precatalysts constitute the source of the ligand and Pd. This work further expands the utility of these precatalysts in reactions that benefit from an easily activated source of L,Pd(0). (C) 2009 Elsevier Ltd. All rights reserved.
