Methyl heptanoate (cas: 106-73-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Application of 106-73-0

Boron-Catalyzed Double Hydrofunctionalization Reactions of Unactivated Alkynes was written by Shibuya, Masatoshi;Okamoto, Masaki;Fujita, Shoji;Abe, Masanori;Yamamoto, Yoshihiko. And the article was included in ACS Catalysis in 2018.Application of 106-73-0 The following contents are mentioned in the article:

In the presence of (C6F5)3B·nH2O, alkynyl alcs. such as HOCH2CPh2CH2CCH underwent tandem hydroalkoxylation and hydroallylation or hydrocyanation reactions with allyltrimethylsilane or cyanotrimethylsilane with H2O as a proton source to yield cyano- and allyl-substituted tetrahydrofurans such as I (R = H2C:CHCH2, NC). The high alkynophilicity of B(C6F5)3 enabled the selective activation of unactivated alkynes in the presence of the alkene moiety of allylsilane and in the presence of cyanide. 19F NMR of intermediate reaction mixtures indicated that alkynes were activated by free (C6F5)3B in allylation reactions and by H+[(C6F5)3BCN–] in cyanation reactions. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Application of 106-73-0).
