DFT and X‐Ray Structural Studies of N(7)‐Tetramethylbenzyl/Pentamethylbenzyl Theophylline Derivatives and Their Catalytic Applications
Theophylline, a naturally occurring xanthine derivative with well‐established pharmaceutical applications, has recently emerged as an attractive scaffold in coordination chemistry and catalysis because of its unique heterocyclic structure and donor properties. In this study, two novel N(7)‐substituted theophylline...
