    Abstract Whereas low‐temperature (−78 °C) reaction of the lithium dithiolene radical1.with boron bromide gives the dibromoboron dithiolene radical2., the parallel reaction of1.with (C6H11)2BCl (0 °C) affords the dicyclohexylboron dithiolene radical3.. Radicals2.and3.were characterized by single‐crystal X‐ray diffraction, UV/Vis, and EPR spectroscopy. The nature of these radicals was also probed computationally. Under mild conditions,3.undergoes unexpected thiourea‐mediated B−C bond activation to give zwitterion4, which may be regarded as an anionic dithiolene‐modified carbene complex of the sulfenyl cation RS+(R=cyclohexyl).
