Although I-methoxy-l -methylseleno-toluene is efficiently metallated by KDA, the same compound as well as its higher homologies react with t-butyllithium producing 1-methoxy benzyllithiumsvia the C-Se bond cleavage.These speciesare efficientlyalkylatedby alkyl halides, even the secondary ones and re
l-Methoxy-benzyllithiums bearing suitably positioned C,C double bonds possess a high propensityto producea five or a six memberedcycle by carbocyclisationreaction.The reaction proceeds completely stereoselectively and produces a five membered cycle possessingthe cis-stereochemistry between the metho
