A green alternative for the conversion of Arylboronic Acids/Esters into phenols promoted by a reducing agent, sodium sulfite
(Wiley VCH Verlag, 2019-05)
Hydroxylation of arylboronic acids and arylboronic esters using sodium sulfite and oxygen as the source of ultimate oxidant proceeds rapidly in water under transition metal-free conditions. This remarkable mild and ...
Changes in pH at the dentin surface in roots obturated with calcium hydroxide pastes
(1996-12-01)
The purpose of this study was to determine the pH, after defined periods of time, in cavities prepared in the facial surface of the cervical, middle, and apical regions of roots obturated with calcium hydroxide pastes. ...
