WebTreatment of 4 with 50 equiv. of DIBAL-H (0.8 )for3h at room temperature gave tetrol 6[14] as the major product in 51% yield. If left for a prolonged period of time but at a lower DIBAL-H concentration (0.4 ), the reaction led to hexol 7[15] as the major compound (45% yield). These re-markable results appear to be in sharp contrast to the case WebAug 3, 2016 · Regio-controlled syntheses of substituted benzenes, naphthalenes, and indenes have been achieved by the DIBAL-H-promoted reaction. 5(k), 9 On the other hand, organoaluminum reagents function as nucleophiles for substitution reactions on sp 3-carbon and silicon centers having a leaving group. 10, 11 This knowledge on …

DIBAL-H, Diisobutylaluminium hydride - Organic Chemistry
Diisobutylaluminium hydride (DIBALH, DIBAL, DIBAL-H or DIBAH) is a reducing agent with the formula (i-Bu2AlH)2, where i-Bu represents isobutyl (-CH2CH(CH3)2). This organoaluminium compound is a reagent in organic synthesis. See more Like most organoaluminum compounds, the compound's structure is most probably more than that suggested by its empirical formula. A variety of techniques, not including X-ray crystallography, suggest that the compound … See more DIBAL is useful in organic synthesis for a variety of reductions, including converting carboxylic acids, their derivatives, and nitriles See more • Stockman, R.
