| abstract |
The invention disclosed and described herein includes compounds of the following formulas (I) and (II) wherein HAr is an optionally substituted 5- or 6-membered heteroaryl ring, Is halogen, and Z is S, Se, NR 5 , C (O), C (O) C (O), Si (R 5 ) 2 , SO, SO 2 , PR 5 , BR 5 , C (R 5 ) is a novel and efficient general method for forming a wide variety of compounds having 2 or 2 (such as P (O) R 5 ). In this synthetic method, a “base-catalyzed halogen dance” reaction is employed to prepare a metalated compound containing a 5- or 6-membered heteroaryl ring containing a halogen atom, and then the reactive intermediate compound is oxidatively coupled. Be ringed. The compounds of formula (II) and / or oligomers or polymers comprising recurring units having the formula (II) are useful for the formation of semiconductor materials and / or electronic devices comprising these materials. |
