The mechanisms of cyclisation and 1,2-bond-shift rearrangements of 2,2,4,4-tetramethylpentane on transition metal films

The cyclisation/rearrangement products 2,2,4,4-tetramethylpentane in deuterium on sintered films of Ir, Rh, Pd, and Pt, analysed by combined gas-liquid chromatography/mass spectrometry, show that chemisorbed carbene and carbyne species are not responsible.
