Aromatization of cyclic hydrocarbons thioether elimination reaction.

Herein, the diversity-oriented aromatization of cyclic hydrocarbons potassium ethyl xanthogenate (EtOCSK)/NHI-mediated methylthiyl radical addition and thioether elimination was investigated under transition-metal-free conditions. The methylthiyl radical species were generated the NHI-mediated decomposition of DMSO following which EtOCSK promoted the breaking of carbon-sulfur bonds of thioether.

[Development of a predicting model of survival rates for patients with salivary adenoid cystic carcinoma].

Objective: To establish a predicting model of survival rates and to evaluate the weighted contributions of each key prognostic factor of the patients with salivary adenoid cystic carcinoma (SACC).

Methods: One hundred and eighteen follow-up cases with SACC were analyzed for the survival study with retrospective cohort method. Ten possible clinical and pathologic factors were selected.
