The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1-Bromo-2-pentyne(SMILESS: CCC#CCBr,cas:16400-32-1) is researched.Reference of Mesitylcopper(I). The article 《The half-sandwich titanocene CpTiIIICl2 as efficient system for the preparation of 2,5-dihydrofurans via α-allenols》 in relation to this compound, is published in Applied Organometallic Chemistry. Let’s take a look at the latest research on this compound (cas:16400-32-1).
The half-sandwich titanocene reagent CpTiIIICl2, obtained by in-situ reduction of com. CpTiCl3 with manganese, was an excellent system for the Barbier-type reaction between aldehydes and propargylic halides, led to homopropargylic alcs. and α-allenols. An efficient and straightforward methodol. for the conversion of aldehydes into 2,5-dihydrofurans involving a two-step sequence (TiIII addition-AgI cyclization) was presented. The usefulness of the method was proved by the preparation of a Natural Product: a dihydrofuranic labdane, isolated from the leaves of Mikania sp. nov.
From this literature《The half-sandwich titanocene CpTiIIICl2 as efficient system for the preparation of 2,5-dihydrofurans via α-allenols》,we know some information about this compound(16400-32-1)Category: tetrahydropyran, but this is not all information, there are many literatures related to this compound(16400-32-1).
