Bromobenzaldehyde isomers Common name and systematic name 2-Bromobenzaldehyde [1] 3-Bromobenzaldehyde [2] 4-Bromobenzaldehyde [3] [4] Structure Molecular formula: C 7 H 5 BrO (BrC 6 H 4 COH) Molar mass: 185.020 g/mol Appearance colorless liquid colorless liquid white solid CAS number [6630-33-7] [3132-99-8] [1122-91-4] Properties Density and ...
3-Bromobenzaldehyde is an isomer of bromobenzaldehyde. It is a colorless viscous liquid. 3-Bromobenzaldehyde can be prepared from 3-nitrobenzaldehyde. [2] See also
4-Bromobenzaldehyde, or p-bromobenzaldehyde, is an organobromine compound with the formula BrC 6 H 4 CHO. It is one of three isomers of bromobenzaldehyde . [ 3 ] It displays reactivity characteristic of benzaldehyde and an aryl bromide .
Amygdalin 2 H 2 O HCN benzaldehyde 2 × glucose 2 × Benzaldehyde contributes to the scent of oyster mushrooms (Pleurotus ostreatus). Reactions Benzaldehyde is easily oxidized to benzoic acid in air at room temperature, causing a common impurity in laboratory samples. Since the boiling point of benzoic acid is much higher than that of benzaldehyde, it may be purified by distillation. Benzyl ...
The product, CH 3 CH(OCH 2 CH 3) 2, is formally named 1,1-diethoxyethane but is commonly referred to as "acetal". [39] This can cause confusion as "acetal" is more commonly used to describe compounds with the functional groups RCH(OR') 2 or RR'C(OR'') 2 rather than referring to this specific compound — in fact, 1,1-diethoxyethane is also ...
One of the bromine substituents is converted to an aldehyde through an S N 2 reaction with the strong base, n-BuLi, and THF in the aprotic polar solvent, DMF to produce 2,5-bis(4-tert-butyldimethylsiloxy-1′-butynyl)-4-bromobenzaldehyde. Another Sonogashira coupling with 3,5-(1′-Pentynyl)-1-ethynylbenzene attaches the lower body of the ...

The resulting product, diethyl 3,5-dimethylpyrrole-2,4-dicarboxylate, has been called Knorr's Pyrrole ever since. In the Scheme above, R 2 = COOEt, and R 1 = R 3 = Me represent this original reaction. Knorr's pyrrole can be derivatized in a number of useful manners. One equivalent of sodium hydroxide will saponify the 2-ester selectively.
