1,4-Dimethoxy-2-butyne (cas: 16356-02-8) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.Recommanded Product: 1,4-Dimethoxy-2-butyne

Rhodium-catalyzed carbon-silicon bond activation for synthesis of benzosilole derivatives was written by Onoe, Masahiro;Baba, Katsuaki;Kim, Yoonjoo;Kita, Yusuke;Tobisu, Mamoru;Chatani, Naoto. And the article was included in Journal of the American Chemical Society in 2012.Recommanded Product: 1,4-Dimethoxy-2-butyne This article mentions the following:

2-(Trimethylsilyl)arylboronic acids undergo rhodium-catalyzed cyclization with internal alkynes, which proceeds with Si-Me bond cleavage and formation of 1-benzosilole heterocycles; the reaction also proceeds readily for catechol and 2,2-dimethyl-1,3-propylene boronate esters, but showed low yields with pinacolboranes. A range of functional groups, encompassing ketones, esters, amines, aryl bromides, and heteroarenes, are compatible, which provides rapid access to diverse benzosiloles. Sequential 2-fold coupling enables modular synthesis of asym. substituted 1,5-dihydro-1,5-disila-s-indacene, a π-extended mol. of interest in organic electronics. In terms of the mechanism, the reaction involves cleavage of a C(alkyl)-Si bond in a trialkylsilyl group, which normally requires extremely harsh conditions for activation. Mechanistic studies, including effects of substituents, reveal that C-Si bond cleavage does not proceed through a hypercoordinated silicon species, but rather through a rhodium-mediated activation process. The potential use of the reaction in catalytic asym. synthesis of Si-chiral benzosiloles is also demonstrated. In the experiment, the researchers used many compounds, for example, 1,4-Dimethoxy-2-butyne (cas: 16356-02-8Recommanded Product: 1,4-Dimethoxy-2-butyne).
