The functionalization of C–H bonds in organic molecules is one of the most direct approaches for chemical synthesis. Recent advances in catalysis have allowed native chemical groups such as carboxylic acids, ketones and amines to control and direct C(sp
The hydrogen-bond acceptor ability of divalent sulfur in Y-S-Z systems, Y, Z = C, N, O or S, and the donor ability of thiol S-H have been studied using crystallographic data retrieved from the Cambridge Structural Database. Of 1811 Y-S-Z substructures that co-occur with N-H or O...
Moreover, Yu and coworkers also successfully achieved the synthesis of functionalized benzolactams by employing acceptor/acceptor diazosubstrates.26In this investigation, a rhodacyclic complex was isolated and its structure was characterized by X-ray crystallography, which would give a direct proof for ...
The selective formation of carbon–carbon bond by functionalization of an sp 3 C–H bond is still a challenge in organic synthesis. There are already examples involving transition metal catalysis. In this chapter we review the use of ruthenium(0) and ruthenium(II) catalysts for the formation of...

(78% ee). We performed in situ1H NMR monitoring on the reaction and observed that the substrate1asuffered rapid oligomerization while the thiophene remained intact. This observation was consistent with the prior findings70that the C–H bond partner was not capable of intercepting the [Rh]-Si ...
