Dataset exploration is an overlooked, but critical area of research in data-driven chemistry. The experimentalist is often blind to the chemical insights that have been locked into these datasets, missing key directions towards areas of exploration. With the development of HiTEA, a meaningful step in addressing this challenge has been made. We uncovered several interesting areas of exploration within Ullmann reactomes and identified several reactomes which would most benefit from additional HTE. We hope that this publication serves as a call to arms to the chemical community to collect, publish and analyze additional chemistry HTE data, providing further opportunities to explore the uncharted territories of the chemical reactome.
