We report the synthesis of a series of eight N → B-ladder boranes through cobalt-mediated cyclotrimerization of (2-cyanophenyl)-dimesitylborane with different dialkynes. The resulting tetracoordinate boranes show variable electrochemical and optical prope

Paragraph 0082, (2019/09/21)
PROBLEM TO BE SOLVED: To provide a new monomer compound from which an optical material can be manufactured that has at least one improved characteristic in a high refractive index and a high glass transition temperature, and a composition for an optical material comprising the above compound. SOLUTION: The present invention discloses a polyfunctional propargyl compound represented by formula (1) below. In the formula, m represents an integer of 3 to 30; R1 represents an alkyl which may have one or more sulfide bonds in the chain, and the alkyl is substituted if necessary; and each RA is independently selected from the group consisting of a hydrogen atom, halogen, alkyl having 1 to 10 carbon atoms, substituted or unsubstituted phenyl, substituted or unsubstituted naphthyl, and silyl.

An efficient protocol for [2,3]-sigmatropic rearrangement of allyl and propargyl thioethers is reported. The key sulfonium ylide intermediate is in situ formed via S-arylation of arynes. This transition metal-free method allows for ready access to a wide
Reactions of HDDA-Derived Benzynes with Sulfides: Mechanism, Modes, and Three-Component Reactions

supporting information, p. 4318 - 4321 (2016/05/09)
We report here reactions of alkyl sulfides with benzynes thermally generated by the hexadehydro-Diels-Alder (HDDA) cycloisomerization. The initially produced 1,3-betaine (o-sulfonium/aryl carbanion) undergoes intramolecular proton transfer to generate a more stable S-aryl sulfur ylide. This can react in various manners, including engaging weak acids (HA) in the reaction medium. This can produce transient ion pairs ArSR2+A- that proceed to the products ArSR + RA. When cyclic sulfides are used, A- opens the ring and is incorporated into the product, an outcome that constitutes a versatile, three-component coupling process.
