Les bis-silanes bis-propargyliques comme précurseurs de bis(vinylidène) oxanes et oxépanes
摘要:
The preparation of bis-silanes Me3SiCH2-C=C-(CH2)(n)-C=C-CH2SiMe3 (n = 1, 2) is described. These silanes allow one to prepare bis(vinylidene)oxanes when n = 1 and bis(vinylidene)oxepanes when n = 2.
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.
