     The dimers 3a- d 0 , 3a- d 5 , and 3a- d 10 were formed in a ratio of 1.00:1.01:0.13, and this ratio gives an isotope effect k H / k D = 7.2 ± 0.8 for the first step of the dimer formation ( A → D , Scheme 4 ). 12 On the basis of the above experimental findings, a probable mechanism for the tandem acetylation/carbocyclizations of arylallene 1 is proposed in Scheme 4 .
