Bismuth (III) sulfide as additive: towards better lubricity without toxicity
(Emerald, 2018-04)
The purpose of this study is to design a fluid formulation with good lubricant properties by using an environmentally friendly additive for: high and low contact pressure conditions and steel/steel and polymer/steel systems. ...
The first bismuth(III)-catalyzed guanylation of thioureas
(Tetrahedron Letters, 2006)
This work describes the first catalytic bismuth-promoted synthesis of polysubstituted guanidines in good yields through the guanylation reaction of N-benzoyl or N-phenylthioureas with primary and secondary amines, but now ...
