Direct observation of a photoinduced Wolff rearrangement in PMMA using ultrafast infrared spectroscopy

Direct observation of a photoinduced Wolff rearrangement in PMMA using ultrafast infrared spectroscopy. Lippert, Thomas; Stoutland, Page O. (Division of Chemical Science and Technology, Los Alamos National Laboratory, Los Alamos, NM, USA). IS&T's Annual Conference, Final Program and Proceedings, 49th, Minneapolis, May 19-24, 1996, 484-486. IS&T--The Society for Imaging Science and Technology: Springfield, Va. (English) 1996.Some commonly used reagents like 7270-63-5 is used in this experiment. CODEN: 64RAAJ. DOCUMENT TYPE: Conference CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Section cross-reference(s): 23 Diazoketones are a widely-used class of compds. for imaging applications; these compds. undergo a photoinduced Wolff rearrangement to form a keto-ketene intermediate (I) which subsequently hydrolyzes to a base-sol. carboxylic acid. As part of a program to develop diagnostics for laser-driven reactions in polymer matrixes, the photo-induced decompn. of 5-diazo-2,2-dimethyl-1,3-dioxane-4,6-dione to I investigated in a PMMA matrix using picosecond IR spectroscopy. The Wolff rearrangement under these conditions is complete in 20 ps. The rapid formation of I is the key element of the high quantum yield of the product acid (2,2-dimethyl-5-oxo-1,3-dioxolane-4-carboxylic acid).In this article, certain chemicals are used. One of their cas registry numbers is 7270-63-5 If the intermediate keto-carbene (II) had a longer lifetime, nonproductive reaction pathways would likely become more important. ..
