AI Technical Summary

Technical Problem

Existing methods for synthesizing α-aminophosphates suffer from limitations such as the use of precious metal catalysts, stringent reaction conditions, and insufficient adaptability to single light sources, which restrict their large-scale application.

Method used

A dual-band bianthracite photocatalyst was developed. By designing and synthesizing 2,9'-bianthracite photocatalysts and using a transition metal-free catalyst, tetrahydroisoquinoline phosphonylacylation was catalyzed to prepare α-aminophosphate compounds under 365 nm and 405 nm light sources.

Benefits of technology

It achieves highly efficient catalytic reactions without the participation of precious metal catalysts, reduces production costs, maintains good compatibility under dual-band light sources, and the catalyst can be recycled with low cycle loss.
