چکیده
The cover picture shows the zwitterionic iminium phosphate [P(C2F5)2F3{C(NEt2)(CHF-CF3)] obtained by reaction of Ishikawa's reagent Et2N-CF2-CHF-CF3 with Lewis-acidic P(C2F5)2F. fluorinating most likely transfers a fluoride ion onto phosphorus center, transiently forming [Et2N=CF-CHF-CF3][P(C2F5)2F2]. α-fluorine atom cation [Et2N=CF-CHF-CF3]+ is labile towards substitution. Subsequently, insertion phosphate(III) anion into activated C−F bond delivers product (https://doi.org/10.1002/zaac.202000198).

متن کاملA new topology for quasi-Z-source inverter
In this paper, a new circuit is proposed for step-up Z-source inverter based on QZSI (quasi-Z-source inverter). The proposed topology inherits all advantages of the conventional topology. The proposed topology in comparison with conventional topology reduces the ST (Shoot-through) duty cycle by over 25% at the same voltage boost factor. Theoretical analysis of the proposed qZSI in the ST and no...
