Multi-Stimuli-Responsive Network of Multicatalytic Reactions using a Single Palladium/Platinum Catalyst

Area of Science:

• Organic Chemistry
• Catalysis
• Biomimetic Chemistry

Background:

• Nature efficiently synthesizes complex molecules and adapts metabolic processes based on cellular needs.
• Chemists aim to replicate nature's ability to control synthetic pathways with external stimuli.

Purpose of the Study:

• To develop a metabolism-inspired, stimuli-responsive multicatalytic system.
• To demonstrate controllable synthesis of diverse products using a single catalytic complex.

Main Methods:

• A multifunctional heteronuclear palladium(II)/platinum(II) complex was synthesized.
• A network of four catalytic reaction classes (cross-couplings, substitutions, additions, reductions) was established.
• Organic starting materials (terminal alkyne, aryl iodide, hydrosilane) were used with controlled addition.

Main Results:

• The catalytic network selectively synthesized ten distinct products.
• Product formation was controlled by specific additives and external stimuli.
• High efficiency and selectivity were achieved through simultaneous triggering and suppression mechanisms.

Conclusions:

• The developed system successfully mimics nature's adaptive metabolic control.
• This approach offers a powerful strategy for controllable and selective organic synthesis.
• The multifunctional catalyst enables orthogonal reaction pathways within a single system.
