The synthesis of 4-formylyphenylboronic acid was reported by the group of Heinrich Nöth in 1990. 4-Bromobenzaldehyde was used as starting material. [2] The acetalization of the aldehyde group was carried out by standard methods [3] using diethoxymethoxyethane and ethanol to give 1-bromo-4-(diethoxymethyl)benzene.

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 ...
4-Ethynylbenzaldehyde may be prepared by the Sonogashira coupling of 4-bromobenzaldehyde with trimethylsilylacetylene to form 4-((trimethylsilyl)ethynyl)benzaldehyde, followed by removal of the trimethylsilyl group with base to form 4-ethynylbenzaldehyde. [3]

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 ...
