Abstract:
We report the anion [Al(NONAr )(Se)]- (NONAr =[O(SiMe2 NAr)2 ]2- , Ar=2,6-iPr2 C6 H3 ), which is an isoelectronic Group 13 metal analogue of the carbonyl group containing an aluminium-selenium multiple bond. It was synthesized in a single step from the reaction of the aluminyl anion [Al(NONAr )]- with elemental selenium. Spectroscopic, crystallographic, and computational analysis confirmed multiple bonding between aluminium and selenium. Addition of a second equivalent of selenium afforded the diselenirane, [Al(NONAr )(κ2 -Se2 )]- , which is an isoelectronic analogue of the dioxirane group.

Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
Nucleophilic Addition to the Carbonyl Group: General Mechanism
A stronger nucleophile can directly attack the electrophilic center, the carbonyl carbon. The HOMO orbital of the nucleophile interacts with the LUMO (π* antibonding) orbital present on the carbonyl carbon. This interaction breaks the π bond and shifts the π...
IR Frequency Region: Alkene and Carbonyl Stretching
Stretching frequencies are affected by several factors, such as resonance, inductive effects, ring strain, dipole moment, and hydrogen bonding. Consequently, the stretching frequency of the carbonyl double bond...
