Bis(trimethylsilyl)acetamide (BSA) is an organosilicon compound with the formula MeC(OSiMe 3)NSiMe 3 (Me = CH 3).It is a colorless liquid that is soluble in diverse organic solvents, but reacts rapidly with moisture and solvents containing OH and NH groups.
Dodecacalcium hepta-aluminate (12CaO·7Al 2 O 3, Ca 12 Al 14 O 33 or C 12 A 7) is an inorganic solid that occurs rarely in nature as the mineral mayenite. It is an important phase in calcium aluminate cements and is an intermediate in the manufacture of Portland cement .
It has the CAS number 68609-97-2 but the IUPAC name is more complex as it is a mixture and is 2-(dodecoxymethyl)oxirane;2-(tetradecoxymethyl)oxirane;2-(tridecoxymethyl)oxirane. [4] Other names include dodecyl and tetradecyl glycidyl ethers and alkyl (C12-C14) glycidyl ether.
The mechanism begins by generation of Si(CH 3) 3 X and a highly reactive [CF 3] − (trifluoromethide) intermediate. The [CF 3 ] − attacks the carbonyl to generate an alkoxide anion. The alkoxide is silylated by the reagent to give the overall addition product, plus [CF 3 ] − , thus propagating an anionic chain reaction.
Structurally, the glutamate anion is zwitterionic, with the amino group protonated (pK a = 9.47) and both carboxylic-acid groups (pK a = 2.10, 4.07) in their deprotonated carboxylate form. [ 6 ] Calcium di- L -glutamate can be used to prepare other glutamates through metathesis with a soluble sulfate, carbonate or hydroxide salt.
Generally, 2-10 mol% of this catalyst is used along with borane-tetrahydrofuran (THF), borane-dimethylsulfide, borane-N,N-diethylaniline, or diborane as the borane source. Enantioselective reduction using chiral oxazaborolidine catalysts has been used in the synthesis of commercial drugs such as ezetimibe and aprepitant .
