  Multicyclic Polyethers Derived from 1,4-Dicyanotetrafluorobenzene and Flexible Diphenols

  摘要：

  1,4-Dicyanotetrafluorobenzene (DCTB) was polycondensed with various diphenols in DMF or DMSO using K2CO3 as catalyst and HF acceptor. At concentrations of 0.1 or 0.2 mol/ L for DCTB, gels were obtained with 1,4-bis[2-(4-hydroxyphenyl)-2-propyl] benzene, with 1,3-bis[(4-hydroxyphenyl)- 2- propyl] benzene and with alpha,omega-bis(4-hydroxyphenoxy) alkanes as comonomers. Yet soluble multicyclic polyethers were formed with alpha,omega-bis(3-hydroxyphenoxy) alkanes. The lengths of the alkane chains did not play any role for the successful syntheses of soluble multicycles. Furthermore, a model reaction with p-cresol was conducted, proving the feasibility of a quantitative tetrasubstitution of all four F-atoms in DCTB. The multicyclic polyethers were characterized by elemental analyses, C-13 NMR spectroscopy, MALDI-TOF mass spectrometry, DSC, viscosity, and SEC measurements. As expected, high polydispersities (up to 8) were found. The DSC measurements indicated an amorphous character of all multicycles with glass-transition temperatures (Tgs) between 75 and 161 degrees C.

  Here we report the first asymmetric synthesis of large chiral macrocycles with chiral sulfur atoms. Building on stereospecific SuFEx and SuPhenEx click chemistries, this approach utilizes disulfonimidoyl fluorides and disulfonimidoyl p-nitrophenolates─which are efficient building blocks with two chiral sulfur centers, and diphenols to efficiently form novel S–O bonds. Characteristic results include
