Paragraph 0290; 0291; 0292; 0293, (2019/04/26)
The organic semiconductor of the present invention comprises a strain type compound represented by the following formula (1). (In the formula, Z represents an atom selected from group 13 to 16 elements in the periodic table rings A 1 and A 2 are rings having at least one carbon-carbon unsaturated bond R 1a , R 1b and R 2 are the same or different and each represents a hydrogen atom or a substituent R 3 represents an atom selected from the group 16 element in the periodic table R A and R B are the same or different and each represents a hydrogen atom, a substituent or an atom selected from the group 16 element in the periodic table m represents an integer of 0 to 4 n represents an integer of 0 to 2 p1 and p2 each represents an integer of 0 or more andrepresents a single bond or a double bond). The organic semiconductor has high mobility (electrical mobility) and can be easily or efficiently molded by a wet process such as coating.

Page/Page column 102, (2018/12/13)
The present invention relates to pyrimidine derivatives of formula (I) wherein (R1)n, R3, R4a, R4b, R5a, R5b and Ar1 are as described in the description and their use in the treatment of cancer by modulating an immune response comprising a reactivation of the immune system in the tumor. The invention further relates to novel benzofurane and benzothiophene derivatives of formula (II) and their use as pharmaceuticals, to their preparation, to pharmaceutically acceptable salts thereof, and to their use as pharmaceuticals, to pharmaceutical compositions containing one or more compounds of formula (I), and especially to their use as modulators of the prostaglandin 2 receptors EP2 and/or EP4.

supporting information; experimental part, p. 12199 - 12206 (2011/02/25)
A general procedure for the preparation of three N-heterocyclic carbene stabilized, boron-containing acenes (9-boraanthracene, 5-boranaphthacene, and 6-borapentacene) is presented. The key steps involve a transmetallation reaction between BCl3 and an appropriate stannacyclic precursor, and the dehydrochlorination of the H2IMes adduct of the chloroborane product. Comparative structural, photophysical, and redox properties reveal narrow HOMO-LUMO gaps relative to the all-carbon acene analogues. Just add boron: Synthetic routes to the N-heterocyclic-carbene-stabilized 5-boranaphthacene and 6-borapentacene are described and complement that previously developed for 9-boraanthracene. Comparative structural, photophysical, and redox properties reveal narrow HOMO-LUMO gaps relative to the all-carbon acene analogues.
Synthesis of biaryls by intramolecular radical transfer in phosphinates
Clive,Kang
, p. 6083 - 6091 (2007/10/03)
Phosphinates 20a-35a give biaryls 20b-35b on heating with stannanes in the presence of AIBN. The process involves a radical ipso substitution on the migrating aryl ring.
A Simple Method of Generating Naphthofuran and Naphthofuran
Smith, James G.,Dibble, Peter W.,Sandborn, Richard E.
, p. 1197 - 1198 (2007/10/02)
Naphthofuran and the novel naphthofuran have been generated from 2-(hydroxymethyl)-1-naphthaldehyde and 3-(hydroxymethyl)-2-naphthaldehyde, respectively, and trapped in Diels-Alder reactions with maleic anhydride.
