Development of a New Catalyst for the Distannation of Alkynes

“…[12] Bel©skii et al were able to crystallize complexes of the type Mo-HSnBu 3 and characterize them by X-ray crystallography in 1986. [13] Brown et al showed that [HMo(CO) 3 Cp] and HSnBu 3 react to form a complex of the type [Bu 3 SnMo(CO) 3 Cp] under reductive elimination of hydrogen. [14] In 1991 Schubert et al observed that [MesCr(CO) 3 ] forms a stable complex with triphenyltin hydride after dissociation of one carbonyl ligand.…”

Entwicklung eines neuen Katalysators zur Distannylierung von Alkinen

“…[12] Erste MoHSnR 3 -Komplexe konnten Bel©skii et al kristallisieren und rˆntgenographisch charakterisieren. [13] [Bu 3 SnMo(CO) 3 Cp] reagiert. [14] [16] sowie die entsprechenden Molybd‰n-und Wolfram-Isonitril-Komplexe C±G .…”

Development of a New Catalyst for the Distannation of Alkynes.

“…[6] The distannation of nonterminal acetylenic esters to (Z)-bis(trimethyltin)alk-2-enoates was achieved by Piers et al in high yields. [13] Brown et al showed that [HMo(CO) 3 Cp] and HSnBu 3 react to form a complex of the type [Bu 3 SnMo(CO) 3 Cp] under reductive elimination of hydrogen. [8] This catalyst is very stable and reliable, and gives high selectivity for the sterically more hindered astannylated product.…”
