Abstract We often pigeonhole our surroundings into dualistic categories. This capacity to function as reductionists may help us problem-solve when pressed in terms of survival or reproduction. Alternatively, binary categories be reflective certain socioecological conditions, and thus social constructs. study explores classifications nonhuman primate taxonomy via the coding human–primate boundar...

Abstract Yndiamides, N,N-disubstituted alkynes, are versatile building blocks for the synthesis of nitrogen-containing organic molecules. Unlike ynamides, relatives that inherently polarized by a single nitrogen substituent, their pseudo-symmetric nature renders regioselective reactions challenging. Here we report investigations into regio­selective addition Brønsted acids to non-symmetric yndi...
