Notes:
Experimental evidence is presented for a unimolecular gas-phase Wagner-Meerwein shift in neopentyl chloride pyrolysis. In the decomposition of α,α-neopentyl chloride-d2 at 445°C, maximally inhibited by cyclohexene, the initial products were isotopically pure 2-methyl-1-butene-d2 and 2-methyl-2-butene-d1. Rearrangement, accompanied by loss of either α- or γ-hydrogen in the formation of hydrogen chloride, is consistent with an incipient ion-pair type of transition state. The cyclohexene maximally inhibited pyrolysis of neopentyl chloride was also examined over the temperature range 424-478°C and Arrhenius parameters of E, 258.7 kJ/mole and logA/sec-1, 13.78, were determined.
