Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated.

Computational exploration of the reaction mechanism of the Cu+-catalysed synthesis of indoles from N-aryl enaminones [PDF]
Royal Society Open Science, 2016 We have studied the role of Cu+-phenantroline as a catalyst in the cyclization of N-aryl-enaminones using density-functional theory computations. The catalyst was found to bind the substrate upon deprotonation of its eneaminone, and to dramatically ...

Manganese(I)‐Catalyzed Dispersion‐Enabled C−H/C−C Activation
, 2017 C-H/C-C Functionalizations were achieved with the aid of a versatile manganese(I) catalyst. Thus, an organometallic manganese-catalyzed C-H activation set the stage for silver-free C-H/C-C transformations with ample substrate scope and excellent levels ...

meta- and para-Selective C–H Functionalization by C–H Activation
, 2015 Transition metal-catalyzed C–H bond functionalization has recently emerged as an indispensable tool for transforming otherwise unreactive C–H bonds. In addition to various strategies for ortho-selective functionalization via chelation assistance, organometallic C–H activation has recently enabled novel functionalizations of (hetero)arenes at remote ...

Electrocatalytic C–H Activation
ACS Catalysis, 2018 C–H activation has emerged as a transformative tool in molecular synthesis, but until recently oxidative C–H activations have largely involved the use of stoichiometric amounts of expensive and toxic metal oxidants, compromising the overall sustainable nature of C–H activation chemistry.
