Tóm tắt

Một quy trình một bước rất hiệu quả để oxi hóa trực tiếp aldehyde thành este dưới sự trung gian của ánh sáng nhìn thấy đã được trình bày. Sử dụng sự kết hợp giữa indium triflate và N-bromosuccinimide (NBS), cùng với ortho-este hoặc rượu, đã cung cấp cách tiếp cận nhanh chóng đến nhiều loại este. Một số cơ chất hoàn toàn biến đổi trong vài giây, trong khi các este tert-butyl khó điều chế hơn có thể được hình thành với năng suất tốt sau không quá 4 giờ.

Từ khóa

#oxit hóa; este; ánh sáng nhìn thấy; aldehyde; indium triflate; N-bromosuccinimide
