General Description

1,1-Diphenylheptane is a chemical compound that belongs to the class of organic compounds known as phenylalkanes. It is a hydrocarbon with the molecular formula C20H26, and its structure consists of a seven-carbon main chain with two phenyl groups attached to the first carbon atom. 1,1-DIPHENYLHEPTANE is a colorless liquid at room temperature and is insoluble in water but soluble in organic solvents. 1,1-Diphenylheptane is primarily used as a synthetic intermediate in the production of various organic compounds and is also employed in research and laboratory settings. It is not known to have any significant commercial or industrial applications outside of the chemical synthesis field.

C(sp3)-H selective benzylic borylation by in situ reduced ultrasmall Ni species on CeO2

Herein, we report that highly dispersed Ni hydroxide species supported on CeO2 act as an efficient heterogeneous catalyst for the selective borylation of benzylic C(sp3)-H bonds of alkylarenes including secondary derivatives, using pinacolborane as the bo

Polyethylene glycol mediated reductive decyanation of diphenylacetonitrile moderately enhanced by microwave heating

An efficient and clean procedure for the preparation of alkyldiphenylmethanes and 4,4-diphenylbutylamines from their corresponding nitriles by using sodium hydroxide-polyethylene glycol reagent system in a domestic microwave oven is described. The products are isolated by simple aqueous work up in excellent yields.

Carbanion Rearrangements by Intramolecular 1,ω Proton Shifts, IV. The Reaction of ω,ω-Diphenylalkyllithium Compounds: Proof for an Intramolecular Transmetallation Reaction by Crossover Experiments Using Isotopic Labelled Starting Material

3,3-Diphenylpropyllithium (2) and 2-(9-fluorenyl)ethyllithium (43) do not show a 1,3 proton shift but splitt off ethylene.On the other hand 4,4-diphenylbutyllithium (19) in diethyl ether can be forced to rearrange to 1,1-diphenylbutyllithium (18) by the addition of THF.The half reaction time for this 1,4 proton shift was found to be about 4 minutes.Proof for the intramolecular character of this transmetallation reaction was obtained by crossover experiments with specifically deuterated starting material.The 1,5 proton shift with 5,5-diphenylpentyllithium (12) occurs considerably slower than the 1,4 shift with 4,4-diphenylbutyllithium (19).The rearrangement also takes place in pure diethyl ether although with a half reaction time of about 2 days.Only 3-(9-fluorenyl)propyllithium (41) in diethyl ether spontaneously shows rearrangement already at -30 deg C, whereby 9-propyl-9-fluorenyllithium (42) is formed by a 1,4 proton shift.A 1,ω phenyl migration according to Grovenstein-Zimmerman in no case could be observed.
