General description

2,4,4-Trimethyl-1-pentene is a α-alkene.[1] It is the main dimeric product of isobutene.[1] Ozonolysis of 2,4,4-trimethyl-1-pentene has been investigated in a flow reactor under pseudo-first-order conditions.[2] Hydrocracking (HCG) of 2,4,4-trimethyl-1-pentene has been employed as a model test reaction to investigate the catalytic functionalities of sulfided CoMo catalysts.[3] Liquid phase oxidation of 2,4,4-trimethyl-1-pentene with molecular xygen afforded epoxides and hydrogen peroxides.[4]
