With respect to acute toxicity, simple alcohols have low acute toxicities. Doses of several milliliters are tolerated. 72824-04-5, formula is C9H17BO2, For pentanols, hexanols, octanols and longer alcohols, LD50 range from 2–5 g/kg (rats, oral). Ethanol is less acutely toxic.All alcohols are mild skin irritants. Category: alcohols-buliding-blocks
Januszewski, Rafal;Grzelak, Magdalena;Orwat, Bartosz;Dutkiewicz, Michal;Kownacki, Ireneusz research published 《 Simple catalytic approach to highly regioselective synthesis of monofunctionalized disiloxanes decorated with metalloids》, the research content is summarized as follows. Selective mono-functionalization of 1,1,3,3-tetramethyldisiloxane (TMDSO) with vinyl and allyl metalloids via hydrosilylation reaction is reported. The activities of a number of transition metal catalysts in the reactions between TMDSO and selected unsaturated metalloids were determined, which permitted selection of the most efficient catalysts whose use led to selective formation of monofunctionalized disiloxanes with the regioselectivity control. All products were isolated and fully characterized by NMR spectroscopy and MS technique.
Category: alcohols-buliding-blocks, 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., 72824-04-5.
