The Performance of GPT-3.5, GPT-4, and Bard on the Japanese National Dentist Examination: A Comparison Study.

Purpose This study aims to evaluate the performance of three large language models (LLMs), the Generative Pre-trained Transformer (GPT)-3.5, GPT-4, and Google Bard, on the 2023 Japanese National Dentist Examination (JNDE) and assess their potential clinical applications in Japan. Methods A total of 185 questions from the 2023 JNDE were used.

Metal-ligand cooperative C-O bond cleavage of propargylic alcohol with protic pyrazole complexes of ruthenium.

The C-O bond cleavage of a propargylic alcohol, 1,1-dimethyl-3-phenylprop-2-yn-1-ol (3), by metal-ligand cooperation was investigated. The reactions of a naphthalene complex [CpRu(η6-C10H8)]PF6 (Cp = η5-C5H5) with 5-R-3-(pyrid-2-yl)pyrazoles (R-LH; R = Ph, CF3) in acetonitrile afforded the starting metal-ligand bifunctional ruthenium complexes [CpRu(R-LH)(MeCN)]PF6 (1a, R = Ph; 1b, R = CF3) featuring an N-N chelate protic pyrazole. The treatment of the CF3-substituted pyrazole complex 1b with 3 in 1,2-dichloroethane at 50 °C resulted in the formation of the η3-butadienyl complex 5.
