Rhodamines as Photocatalyst in Organic Synthesis

Abstract

Organic synthesis, under environment-friendly conditions, has a great impact on sustainable development. In this context, visible light photocatalysis has emerged as a green model, as this offers an energy-efficient pathway towards the organic transformation. Different transition-metal catalysts (Ir-, Ru-, Cu- etc.) and organic dyes (eosin Y, rose bengal, methylene blue, etc.) are wellknown photocatalysts in organic synthesis. Apart from the well-known organophotoredox catalysts, rhodamines (Rhodamine B and Rhodamine 6G) have also been employed as efficient photocatalysts for different organic transformations. In this review, we will focus on the photocatalysis by rhodamines in organic synthesis. The mechanistic pathway of the methodologies will also be discussed. We believe this review will stimulate the employment of rhodamines in the visible light photocatalysis for efficient organic transformations in the future.
