Abstract
Whereas low-temperature (-78 °C) reaction of the lithium dithiolene radical 1. with boron bromide gives the dibromoboron dithiolene radical 2. , the parallel reaction of 1. with (C6 H11 )2 BCl (0 °C) affords the dicyclohexylboron dithiolene radical 3. . Radicals 2. and 3. 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 zwitterion 4, which may be regarded as an anionic dithiolene-modified carbene complex of the sulfenyl cation RS+ (R=cyclohexyl).
