Cluster FLPs (CFLPs) offer enhanced cooperative effects for superior catalysis. This study introduces novel CFLPs with a MoIV3 Lewis acidic cluster and SbIII Lewis base, improving catalytic efficiency.
Area of Science:
- Catalysis
- Materials Science
- Inorganic Chemistry
Background:
- Frustrated Lewis pairs (FLPs) are powerful bifunctional catalysts utilizing Lewis acid-base synergy.
- Traditional FLPs often lack cooperative effects due to single-atom Lewis components.
Purpose of the Study:
- To develop cluster FLPs (CFLPs) with enhanced cooperative effects.
- To investigate the catalytic performance of novel CFLPs.
Main Methods:
- Synthesis of a novel cluster FLP: H[SbIII3MoIV3MoVI15O55(OH)2py3] (1).
- Characterization of the CFLP structure and components.
- Evaluation of catalytic activity.
Main Results:
- Developed CFLPs comprising a triangular MoIV3 Lewis acidic cluster and an SbIII Lewis basic partner.
- Demonstrated extensive cooperative actions within the MoIV3 cluster and between MoIV3 and SbIII.
- Achieved excellent catalytic performance with the developed CFLP system.
Conclusions:
- The developed CFLPs exhibit superior catalytic efficiency due to enhanced cooperative effects.
- This work provides a new strategy for designing highly efficient FLP catalysts.

02:36Regioselectivity 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.

The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
