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.

Mori-Quiroz, Luis M.;Comadoll, Chelsea G.;Super, Jonathan E.;Clift, Michael D. research published 《 Exploiting Iminoquinones as Electrophilic at Nitrogen “N+” Synthons for C-N Bond Construction》, the research content is summarized as follows. New methods for C-N bond construction exploiting the N-centered electrophilic character of iminoquinones were reported. Iminoquinones, generated in situ via the condensation of o-vinylanilines with benzoquinones, underwent acid-catalyzed cyclization to afford N-arylindoles I [R = H, F; R1 = H, Me, Ph, etc.; R2 = H, Me; R3 = H, Cl, CO2Me, etc.; Ar = 3,5-di-(t-Bu)-4-OHC6H2, 3,5-di-Me-4-OHC6H2, 3,5-di-(t-Bu)-2-OHC6H2, 10-hydroxy-9-phenanthryl] in excellent yields. Under similar reaction conditions, homoallylic amines reacted analogously to afford N-arylpyrroles II [R4 = Ph, 3-MeOC6H4, 4-FC6H4, 2,6-di-FC6H3, 2,3-dihydrobenzofuran-5-yl; R5 = H, 4-MeC6H4; Ar = 3,5-di-(t-Bu)-4-OHC6H2]. Addnl., organometallic nucleophiles were shown to add to the nitrogen atom of N-alkyliminoquinones to provide amine products. Finally, iminoquinones were shown to be competent electrophiles for copper-catalyzed hydroamination.
