Transition-metal catalyzed C-H bond functionalization have emerged as a powerful synthetic method and been extensively reported.[1] Recently,Chatani et al [2]reported the rhodium-catalyzed reaction of t-butyl aryl 2-pyridyl ether(R)with bis(pinacolato)diboron(B2(pin)2)leading to the arylboronic acid derivatives via activation of the C(aryl)-O bonds.
