In general, the hydroxyl group makes alcohols polar. 72824-04-5, formula is C9H17BO2, Because of hydrogen bonding, alcohols tend to have higher boiling points than comparable hydrocarbons and ethers. Name: 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane
Peranantham, Pazhanisami;Jeyachandran, Yekkoni Lakshmanan research published 《 Sub-2 nm boron doping in silicon using novel ultra-thin SiO2 film produced by sol-gel dip coating as a capping layer》, the research content is summarized as follows. Advancements in semiconductor electronics and sensor technologies demand a more robust doping approach and process to fabricate ultra-shallow doping with abrupt depth, particularly on complex structured surfaces. Mol. monolayer doping (MLD) is a potential approach, but is limited by the difficulty in depositing a high-quality SiO2 capping film without damaging the dopant mol. layer. In this work, a relative humidity condition during deposition of the film in the sol-gel dip-coating process is found to produce continuous, dense and stoichiometric ultra-thin SiO2 films of quality equivalent to that produced by complicated thermal oxidation/etching and sophisticated chem. vapor deposition and at. layer deposition methods. Applying these ultra-thin SiO2 films as capping layers in the mol. MLD method, B doping in Si with sub-2 nm effective depth and sub-5 nm abrupt depth is achieved. Remarkably, around 82%-86% of doped B atoms in Si are found to be elec. active as estimated from sheet resistance measurements. The established sol-gel dip coating conditions to deposit ultra-thin SiO2 films are generic and can be extended to produce high-quality ultra-thin films of other metal oxide materials required for advanced technol. applications.
72824-04-5, Allylboronic acid pinacol ester is a useful research compound. Its molecular formula is C9H17BO2 and its molecular weight is 168.04 g/mol. The purity is usually 95%.
Allylboronic acid pinacol ester is an allylation reagent that is used to produce aldehydes from ketones. It reacts with water, yielding the desired product and formaldehyde as a byproduct. The reaction proceeds through a sequence of steps, in which the boronate ester first reacts with water to form an allylboronate ion and hydrogen gas. This intermediate then reacts with potassium t-butoxide to produce the desired allyl alcohol and potassium borohydride. Finally, the palladium complex catalyst reduces the carbonyl group of the starting material, converting it into an aldehyde. Allylboronic acid pinacol ester is commercially available as a white solid, but can also be synthesized from 2-chloro-5-pinacolylborane (pinacol) in high yield using catalytic cross coupling reactions., Name: 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane
