A photochem. method for converting aliphatic alcs. into boronic esters is described. Preactivation of the alc. as a 2-iodophenyl-thionocarbonate enables a novel Barton-McCombie-type radical deoxygenation that proceeds efficiently with visible light irradiation and without the requirement for a photocatalyst, a radical initiator, or Sn or Si hydrides. The resultant alkyl radical is intercepted by bis(catecholato)diboron, furnishing boronic esters from a diverse range of structurally complex alcs. In the experiment, the researchers used many compounds, for example, 3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3Quality Control of 3-(3,4-Dimethoxyphenyl)propan-1-ol).
3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. Electron-deficient reagents are also stabilized by ethers. For example, borane (BH3) is a useful reagent for making alcohols. Pure borane exists as its dimer, diborane (B2H6), a toxic gas that is inconvenient and hazardous to use. Borane forms stable complexes with ethers, however, and it is often supplied and used as its liquid complex with tetrahydrofuran (THF).Quality Control of 3-(3,4-Dimethoxyphenyl)propan-1-ol
