tert-Butyl acetoacetate (TBAA)

tert-Butyl Acetoacetate, kuma aka sani da TBAA, ester ce ta kwayoyin halitta tare da Lambar CAS 1694-31-1. Wannan ruwa mara launi zuwa kodadde rawaya ko ɗan rawaya bayyanan ruwa yana da ƙamshi na 'ya'yan itace kuma ana siffanta shi da tsarin sa na β-ketoester, wanda ke ba da damar amsawa ta musamman. Yana da ɗan narkewa a cikin ruwa amma sosai mai narkewa a cikin kaushi na halitta kamar xylene.

TBAA ya fi sterically hanawa fiye da methyl ko ethyl acetoacetate analogs, sau da yawa samar da mafi girma reactivity da selectivity a transacetoacetylation da sauran roba canji.
