Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 188111-79-7, Name is (R)-1-Boc-3-Aminopiperidine, molecular formula is , belongs to piperidines compound. In a document, author is Savkov, Boris Y., Product Details of 188111-79-7.
Unusual Synthesis of Triosmium Carbene Clusters by Tandem Activation of Chlorohydrocarbons and Heterocyclic Amines
Reactions of the [Os3H2(CO)(10)] cluster complex (1) with six-membered heterocyclic amines (morpholine, thiomorpholine, piperidine) and halohydrocarbons (CH2Cl2, ClHC=CHCl, CH2=CCl2) at similar to 25 degrees C have been studied. Two main types of products are formed in all studied reactions. One product is carbene cluster [Os-3(mu-H)(mu-Cl){eta(1)-C(CH3)N(CH2CH2)(2)X}(CO)(9)] (X=O, S, CH2) (3, 3 a and 3 b). Second product is cluster containing enamine ligand [Os-3(mu-H){mu-CH=CHN(C2CH2)(2)X)}(2)(CO)(10)] (X=O, S, CH2) (2, 2 a and 2 b). The carbene ligand is assembled on a cluster, from three organic molecules, thus representing the first example of carbene ligands formed in this way. Clusters with carbene ligand exist as two stable isomers (rotamers hindered towards the Os-C bond), as confirmed by NMR studies and conformational analysis. We have found that in reactions of cluster 1 with acyclic amines containing an oxygen atom in gamma-position (likely morpholine in CH2Cl2), only complexes with bridging enamine ligands are formed. Compounds 2 a, 2 b, 3 and 3 b are characterized by single-crystal X-ray diffraction.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 188111-79-7, in my other articles.
