We found recently that a C-C bonding phenyl-quinone product was produced with high yield (96%) from the reaction between 2,5-dichloro-1,4-Benzoquinone (DCBQ) and N-phenylbenzohydroxamic acid (N-PhBHA) via an unusual Claisen rearrangement mechanism, accompanied with the concurrent formation of the minor byproducts amide (N-phenylBenzamide, N-PhBA; only 2% yield) and hydroxychloroquinone (2% yield). Surprisingly, when DCBQ was replaced with its reduced form 2,5-dichloro-1,4-hydroquinone (DCHQ), no C-C bonding product was detected, whereas N-PhBA (83% yield) and hydroxychloroquinone (80% yield) became the predominant products, indicating a dramatic mechanistic shift. The ascorbate reduction experiment suggested that it was not DCHQ itself, but its corresponding semiquinone radical, that directly reacts with N-PhBHA.

Center for Applied Statistics, School of Statistics, Renmin University of China, No. 59 Zhongguancun Street, Beijing, 100872, P.R. China.

Previous studies have identified attenuated pre-speech activity and speech sound suppression in individuals with Schizophrenia, with similar patterns observed in basic tasks entailing button-pressing to perceive a tone. However, it remains unclear whether these patterns are uniform across individuals or vary from person to person. Motivated by electroencephalographic (EEG) data from a Schizophrenia study, we develop a generalized functional linear mixed model (GFLMM) for repeated measurements by incorporating subject-specific functional random effects associated with multiple functional predictors.
