2,6-Diphenylpyrylium and 2,6-di-t-butylpyrylium perchlorates are easily converted into a number of the corresponding 4-alkyl derivatives by photochemical reaction with tetraalkylstannanes, in MeCN at room temperature.The mechanism of the process is discus

2,6-Diaryl-4H-(benzotriazolyl)pyrans (7a-c) on treatment with n-butyllithium undergo smooth lithiation at the position α to the benzotriazolyl moiety. In contrast to fused and bridged pyranyl derivatives, these pyranyl anions react with electrophiles by t
