WebMar 27, 1998 · It has been shown that cyclopropenyl radicals dimerize to form the corresponding bicycloprop-2-enyl derivatives 4′C. Surprisingly, anti -tricyclohexylene 3′C , which is best described as a singlet biradical, is calculated to have an energy only 83 kJ/mol above that of the previously isolated ( 3 ) C–C σ-dimer 4′C.

WebOct 22, 2014 · For cyclopropene itself the pKa is 61, for trimethylcyclopropene it is 74, while for tri-t-butylcyclopropene it is 73. For triphenylcyclopropene it is 50, essentially the same as that determined with the slower method since the coupling of its more stabilized hindered radicals is slower.
