A general manganese catalyzed chemoselective semihydrogenation of alkynes R1CCR2 (R1 = Ph, 4-bromophenyl, 4-methoxyphenyl, 4-[methoxy(oxo)methane]phenyl, etc.; R2 = Ph, 4-chlorophenyl, 2-amino-5-chlorophenyl, pyridin-3-yl, etc.) to olefins R1HC=CHR2 in the presence of mol. hydrogen is described. The best results are obtained by applying the aliphatic Mn PNP pincer complex Mn-3c which allows the transformation of various substituted internal alkynes to the resp. Z-olefins under mild conditions and in high yields. Mechanistic investigations based on experiments and computations indicate the formation of the Z-isomer via an outer-sphere mechanism. In addition to this study using Bromopentacarbonylmanganese(I), there are many other studies that have used Bromopentacarbonylmanganese(I)(cas: 14516-54-2Category: bromides-buliding-blocks) was used in this study.
Bromopentacarbonylmanganese(I)(cas: 14516-54-2) has many other uses. It is used in the formation of (eta6-arene)tricarbonylmanganese(I) by reacting with arene (arene= hexamethyl benzene, 1,2,4,5-tetramethyl benzene, mesitylene, p-xylene and toluene) in the presence silver salt.Category: bromides-buliding-blocks
