Abstract Achieving precise control over regioselectivity and stereoselectivity in the hydroelementation of terminal allenes presents a formidable challenge. Despite existence various catalytic methods for their functionalization, this entire class reactions remains significantly underdeveloped demands extensive research. Here, we report method using inexpensive PN 5 P pincer cobalt complexes built on triazine backbone. Depending substituent at ring, enables selective synthesis E‐alkenylsilane or Z‐allylborane derivatives. In presented approach, silanes pinacoloboranes play dualistic role simultaneous activator substrate excluding need addition external bases. Finally, application potential obtained compounds was demonstrated by performing further functionalizations compounds.
