Current Organic Synthesis | Cas: 2235-01-0 was involved in experiment

Dimethoxydiphenylmethane is one of ethers-buliding-blocks. 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. Electric Literature of C15H16O2 The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.

Electric Literature of C15H16O2《Hafnium(IV) Chloride Catalyzes Highly Efficient Acetalization of Carbonyl Compounds》 was published in 2019. The authors were Bonilla-Landa, Israel;Lopez-Hernandez, Emizael;Barrera-Mendez, Felipe;Salas, Nadia C.;Olivares-Romero, Jose Luis, and the article was included in《Current Organic Synthesis》. The author mentioned the following in the article:

Hafnium(IV) tetrachloride efficiently catalyzes the protection of a variety of aldehydes and ketones RC(O)R1 (R = Ph, 4-butylphenyl, pyridin-2-yl, octyl, etc.; R1 = H, Me, Et), including benzophenone, acetophenone, and cyclohexanone, to the corresponding di-Me acetals and 1,3-dioxolanes, RC(OR2)2R1 (R2 = Me, -(CH2)2-) under microwave heating. Substrates possessing acid-labile protecting groups (TBDPS and Boc) chemoselectively generated the corresponding acetal/ketal in excellent yields.Dimethoxydiphenylmethane (cas: 2235-01-0) were involved in the experimental procedure.
