Synthetic Route of C7H15BrO2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2-Bromopriopionaldehydediethylacetal, is researched, Molecular C7H15BrO2, CAS is 3400-55-3, about Competitive processes in the hydration of dicarbonyl η5-(cyclopentadienyl) alleneiron cations. Author is Klemarczyk, Philip; Rosenblum, Myron.

Hydration of CpFe(CO)2(CH2:C:CH2) under acidic conditions gives a mixture of CpFe(CO)2CH2COMe and CpFe(CO)2CHMeCHO. The aldehyde complex is derived by acid-catalyzed rearrangement of an allyl alc. complex in a process involving a metal-stabilized cation.
