Abstract
AbstractAchieving precise control over regioselectivity and stereoselectivity in the hydroelementation of terminal allenes presents a formidable challenge. Despite the existence of various catalytic methods for their functionalization, this entire class of reactions remains significantly underdeveloped and demands extensive research. Here, we report a method for the hydroelementation of allenes using inexpensive PN5P pincer cobalt complexes built on a triazine backbone. Depending on the substituent at the ring, the method enables the selective synthesis of E‐alkenylsilane or Z‐allylborane derivatives. In the presented approach, silanes and pinacoloboranes play a dualistic role of simultaneous activator and substrate excluding the need for the addition of external bases. Finally, the application potential of the obtained compounds was demonstrated by performing further functionalizations of the obtained compounds.
