Application
- Copolymerization of β‐butyrolactones using DMAP as initiator: This research focuses on the use of DMAP in the ring-opening polymerization of β‐butyrolactones, analyzing its efficiency as a catalyst (Palenzuela et al., 2024).
- Halogen-Bond-Promoted Direct Cross-Coupling: This article details the use of DMAP in a catalytic process for the cross-coupling of alkyl bromides with coumarins, emphasizing its role under light illumination (Guo et al., 2024).
- Enantiospecific Analysis of Carboxylic Acids: Discusses the superior efficacy of DMAP compared to other catalysts like Et3N in the enantiospecific analysis of carboxylic acids (Mo et al., 2024).
