Both are precursors to plasticizers. [2] The isononylol ( 3,5,5-trimethyl-hexan-1-ol ) is a precursor to 3,5,5-trimethylhexyl acetate, a commercial fragrance. [ 3 ] Diisobutenes were once of interest as components for automotive fuels.
More recently, for the reductive silylation of N 2, sodium has been used instead of lithium as the electron donor and molybdenum [19] and iron compounds [3] (such as pentacarbonyl iron or ferrocenes [20]) as catalysts, up to 34 equivalents of N(Me 3 Si) 3 could be obtained per iron atom in the catalyst.
Bromobimane is prepared from 3,4-dimethyl-2-pyrazolin-5-one (a condensation product of ethyl 2-methylacetoacetate with hydrazine) by chlorination followed by basic treatment; with aqueous K 2 CO 3 under heterogeneous conditions, the required syn-bimane, 2,3,5,6-tetramethyl-1H,7H-pyrazolo[1,2-a]pyrazole-1,7-dione, is the major product.
3,5,5-Trimethyl-1-hexanol is a nine carbon primary alcohol, and it makes up the mixture isononanol along with isononyl alcohol. It is used for fragrance in many toiletries and household cleaning products. Between one and ten metric tonnes are produced every year for use as a fragrance. [1]
