Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. 122775-35-3, formula is C8H11BO4, Name is 3,4-Dimethoxyphenylboronic acid. Ethers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. Formula: C8H11BO4.
Schmidt, Tanno A.;Sparr, Christof research published 《 Catalyst-Controlled Stereoselective Barton-Kellogg Olefination》, the research content is summarized as follows. Herein, the direct catalyst control is achieved by a stereoselective Barton-Kellogg olefination with enantio- and diastereocontrol for various bistricyclic aromatic enes I (R = H, F, Br, 2,6-dimethoxyphenyl; R1 = H, Me, Ph, 3,5-dichlorophenyl, etc.) was reported. Using Rh2(S-PTAD)4 as catalyst, several diazo compounds II were selectively coupled with a thioketone to give one of the four anti-folded overcrowded alkene stereoisomers I upon reduction Complete stereodivergence was reached by catalyst control in combination with distinct thiirane reductions to provide all four stereoisomers I (R = H, R1 = 3,5-dimethoxyphenyl) with e.r. values of up to 99:1. This strategy will enable the synthesis of topol. unique overcrowded alkenes I for functional materials, catalysis, energy- and electron transfer, and bioactive compounds
