A Facile Route to 1,4-Disubstituted Benzocyclobutenes
摘要:
By [2+2] cyclization and elimination of an alcohol moiety, the diallenyldiethers, prepared through allenylation reaction of acetals with 1,8-bis(trimethylsilyl)-2,6-octadiyne, lead by heating to 1,4-disubstituted benzocyclobutenes, in good yields.
