This correction clarifies nitro-redox reactions involving frustrated Lewis pairs. It ensures accurate representation of chemical interactions and reaction mechanisms in borane/phosphane systems.
Area of Science:
- Chemistry
- Inorganic Chemistry
- Organic Chemistry
Background:
- Frustrated Lewis pairs (FLPs) are reactive species that do not form classical adducts.
- Borane and phosphine compounds are key components in FLP chemistry.
- Nitro-redox reactions involve the reduction or oxidation of nitro groups.
Purpose of the Study:
- To correct inaccuracies in the original publication regarding nitro-redox reactions.
- To provide a precise account of the reactivity of a specific frustrated borane/phosphane Lewis pair.
- To ensure the scientific record accurately reflects the experimental findings.
Main Methods:
- Spectroscopic analysis (e.g., NMR) to characterize reaction products.
- Computational modeling to understand reaction pathways.
- Re-evaluation of experimental data presented in the original study.
Main Results:
- The correction addresses specific details of the nitro-redox reaction mechanism.
- Revised characterization data confirms the proposed intermediates and products.
- The corrected study clarifies the role of the frustrated Lewis pair in the reaction.
Conclusions:
- The corrected findings provide a more accurate understanding of frustrated Lewis pair chemistry.
- Accurate reporting of nitro-redox reactions is crucial for advancing FLP applications.
- This correction ensures the integrity of scientific literature in the field.

Hydroboration-Oxidation of Alkenes
Regioselectivity and Stereochemistry of Hydroboration
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn stereochemistry.

A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...
