Abstract

The solution phase photochemistry of the sterically congested tetramethylated benzobarrelene derivative 2b differs completely from that of its non-methylated counterpart, 2a. Based on molecular mechanics calculations, the factor that is suggested to be responsible for this difference is relief of the unfavorable methyl-methyl interactions present in 2b.
