Diisopropyl azodicarboxylate - Wikipedia
Diisopropyl azodicarboxylate (DIAD) is the diisopropyl ester of azodicarboxylic acid. It is used as a reagent in the production of many organic compounds. It is often used with triphenylphosphine in the Mitsunobu reaction, [2] wherein it serves as a hydride acceptor. It has also been used to generate aza- Baylis-Hillman adducts with acrylates. [3]

To solve the above problems, we propose a Difusion-based Anomaly Detection (DiAD) framework for multi-class anomaly detection, which consists of a pixel-space autoencoder, a latent-space Semantic-Guided (SG) network with a connection to the stable diffusion’s denoising network, and a feature-space pre-trained feature extractor.

Mitsunobu reaction - Wikipedia
The Mitsunobu reaction is an organic reaction that converts an alcohol into a variety of functional groups, such as an ester, using triphenylphosphine and an azodicarboxylate such as diethyl azodicarboxylate (DEAD) or diisopropyl azodicarboxylate (DIAD). [1] Although DEAD and DIAD are most commonly used, there are a variety of other ...
