Spectroscopic Characterization of the 1-Boratricyclo-[4.1.0.0^2,7]-heptane Radical with a Delocalized Four-Center-One-Electron Bond.

ABSTRACT: The boron atom is a highly electrophilic reagent due to the presence of its empty p orbital, making it prone to undergo electrophilic addition reactions with the carbon-carbon double bonds of olefins. In this study, the classical C=C reaction pathway occurs when a boron atom attacks the C=C bond of cyclohexene, resulting in the formation of the η² (1,2)-BC₆H₁₀ complex (A) that contains a borirane radical subunit. This complex can further undergo photoisomerization, leading to the formation of a 3,4,5,6-tetrahydroborepine radical (C) through the cleavage of C-C bonds. In addition, two 1-boratricyclo[4.1.0.0^2,7]heptane radicals with chair (B) and boat (B') conformations were observed through α C-H cleavage reactions. Bon
