The facile synthesis of aminoallenes, accomplished by a selenium-π-acid-catalyzed cross-coupling of an N-fluorinated sulfonimide with simple, non-activated alkynes, is reported. Until now, aminoallenes were difficult to be accessed by customary means, inasmuch as pre-activated and, in part, intricate starting materials were necessary for their synthesis. In sharp contrast, the current study shows that ordinary internal alkynes can serve as simple and readily available precursors for the construction of the aminoallene motif. The operating reaction conditions tolerate numerous functional groups such as esters, nitriles, (silyl)ethers, acetals, and halogen substituents, furnishing the target compounds in up to 86 % yield.

Paragraph 0044; 0045; 0046, (2018/06/16)
The invention discloses an organic small molecular semiconductor material containing anthracene dithiophene as well as a preparation method and an application thereof. The structural formula of the material is as shown in a formula I, wherein the unit A is an electron deficient group; R1 is hydrogen or alkyl with 1-30 carbon atoms or a group in the alkyl with 1-30 carbon atoms, one or more of which are replaced by halogen atoms, oxygen atoms, alkenyl, alkynyl, aryl, hydroxyl, amino, carboxyl, ester groups, cyan or nitryl. The material has unique advantages of relatively good light capturing ability, proper electronic energy level, relatively high electronic mobility and the like, and is applied to organic solar battery apparatuses as an electron acceptor material to obtain good apparatus performances.

No catalyst pre-activation, no suicide alkyne, and no additive is required in an extremely simple procedure for the metathesis of alkyl-, alkenyl-, and aryl-propynes: just mix Mo(CO)6, p-chlorophenol, and the alkyne in 1,2-dichloroethane, heat at 85°C for 9-24 h, and the symmetrical alkyne is produced in ca. 95% yield.
