  A New General Route to Thiophenophanes:  Synthesis and Properties of [n](2,5)Thiophenophane-1,n-diones

  摘要：

  A series of [ n]( 2,5) thiophenophane-1, n-diones ( 5) ( n = 9, 10, 12, 14, 16, and 20) were synthesized in a simple four-step route starting from the appropriate 1,omega-oligomethylenedicarboxylic acids. The bis-( halomethylketones) ( 6), which were obtained by successive treatment of the diacids with SOCl2, diazomethane, and HBr or HCl, were cyclized by Na2S under high dilution conditions. The obtained monomeric cyclic diketosulfides ( 4) were condensed with glyoxal in MeOH by slowly adding dilute NaOMe affording 5. The thiophene-2,5-dicarbonyl moiety of 5 ( n = 9) is significantly deformed as shown by X-ray crystallography, and the effect of the strain is reflected in the C=O stretching frequencies and the pi-pi* and the n-pi* absorptions.
