Machine-learning methods have great potential to accelerate the identification of reaction conditions for chemical transformations. A tool that gives substrate-adaptive conditions for palladium (Pd)-catalyzed carbon-nitrogen (C-N) couplings is presented. The design and construction of this tool required the generation of an experimental dataset that explores a diverse network of reactant pairings across a set of reaction conditions.

An alkoxylation of ()- with ()--methylprolinol () and a global deprotection generates the penultimate heterobiaryl intermediate .

Although we strongly support Scott et al.

In two studies, we use developmental and social theories to ground an exploration of Dominican children's racial biases. In studies 1 ( = 54; ages 6-11) and 2 ( = 122; ages 6-11), children were given measures of racial identity, preference, stereotyping, and/or status.
