Tuning reactivity through implementation of the HSAB concept in oxygen- and sulphur-bridged Al/P and Ga/P FLPs

Key Points

• The research aims to explore how the HSAB (hard and soft acids and bases) concept influences the reactivity of sulphur- and oxygen-bridged frustrated Lewis pairs.
• Synthesis of sulphur-bridged and oxygen-bridged frustrated Lewis pairs.
• Comparison of reactivity between analogues AlSP and EOP.
• Analysis of exchange reactions occurring in different bridging scenarios.
• The sulphur-bridged Lewis pairs exhibit tunable reactivity based on the HSAB concept.
• Notable differences in reactivity patterns were observed when compared to oxygen-bridged analogues.
• Specific exchange reactions between the pairs demonstrated effective tuning of chemical behavior.
