In this paper, the ring-opening reaction of 2,5-dioctyldithieno[2,3-b:3',2'-d]thiophene with aryllithium in THF at low temperature to generate 2'-arylthio-3,3'-bithiophene-2-carbaldehydes is studied. Nine examples are explored and all the products are characterized by (1)H NMR, (13)C NMR and HRMS. The relative relationship between the structures of aryl(More)
Volatile organic compounds( VOCs) from cooking can affect air quality indoor and outdoor. The compositions of VOCs from cooking in the Northeast Area of China were investigated by using the method of pre-concentration-GC-MS. The average mass concentration of VOCs from cooking was 3407.06&#x00B1;889.5 &#x00B5;g.m<sup>&#x2212;3</sup>, which is 1.7 times of(More)
With 3,3'-bi[benzo[b]thiophenyl] as starting material, dibenzo[d,d']benzo[1,2-b:4,3-b']dithiophene, a [5]heterohelicene, was synthesized efficiently in 60% yield via formylation and McMurry reaction. Cyclopenta[1,2-b:4,3-b']bis(benzo[d]thiophen)-6-one, another interesting helical ketone, was also prepared in 79% yield via deprotonation and ketonization of(More)
