Reaction between ethyl-lithium and α-methylstyrene in benzene at 30°; formation of 1,3-dimethyl-3-phenyl-1-propylindane
Abstract
Oligo-α-methylstyryl-lithium compounds formed from the reaction between α-methylstyrene and ethyl-lithium decompose slowly in benzene at room temperature to give lithium hydride and substituted indanes. With equimolar concentrations of the two reactants, the main organic product is 1,3-dimethyl-3-phenyl-1-propylindane.
