Penentuan Koefisien Distribusi, Efisiensi Ekstraksi Dan Faktor Pemisahan Pada Ekstraksi Gadolinium Dan Samarium Dengan Ligan Dibutilditiofosfat

“…Dalam studi mengenai kromatografi logam-logam transisi, Bahti et al (1990) telah menggunakan ligan dialkilditiofosfat sebagai ligan pengompleks dalam tahap ekstraksi logam tersebut. Unsur-unsur lantanida dapat membentuk senyawa khelat yang baik dengan senyawa asam fosfat, asam fosfit dan tributilfosfat, oleh karena itu senyawa-senyawa ligan tersebut dapat digunakan untuk mengekstraksi unsur-unsur lantanida (Ozturk et al, 2010).…”

Synthesis of orthogonally protected thioamide dipeptides for use in solid-phase peptide synthesis

“…6 The synthesis of thioamides has been reviewed, and one of the principal methods used is the thionation of amides. 7 A large number of methods have been developed for the thionation of carbonyl groups to their thiocarbonyl analogues, where the main reagents include Lawesson's reagent, 8 Berzelius' reagent 9 , more recently Curphey's method. 10 The use of a P4S10-pyridine complex was also reported by Bergman and co-workers in 2011.…”

Fused Thiophenes and Some Oligomers and Polymers Therefrom

“…The synthesis of 231 was achieved in three steps starting from 1,1,2,2-tetrabenzoylethane (232) thus double ring closure using P 4 S 10 [89], produced 233, treatment with NaIO 4 then yielding the sulfoxide 234 and dehydration with acetic anhydride furnished 231 (Scheme 56) [86,87]. Tetra(thien-2-yl)thieno [3,4-c] thiophene (237), a dark purple (λ max 576 nm), stable crystalline substance, was made in similar fashion (Scheme 57) [12].…”

“…The DTTs (317), possessing para substituted phenyl groups at the 3-and 4-positions, were made available through ring closure of diketones (316) using P 4 S 10 [89] (Scheme 79) [127]. DTT (247) has been electropolymerized on ITO [103,131,133].…”
