Among the frontier challenges facing synthetic chemistry in the 21st century are the
interconnected goals of increasing control of chemical reactivity and synthesizing
complex molecules with higher levels of efficiency. Catalytic C–H bond functionalization
reactions are increasingly being discovered that meet the criterion for useful reactivity
(i.e. preparative, predictably selective, and general). Consequently, such reactions
are enabling chemists to exploit strategies for complex molecule synthesis and derivatization
previously accessible only in nature. This preface highlights some of the achievements
and important challenges that remain in the area of C–H bond functionalization.�
