Reactions of coordinated hydroxymethylphosphines with NH-functional amines: the phosphorus lone pair is crucial for the phosphorus Mannich reaction.
Non-coordinated hydroxymethylphosphines react readily with primary and secondary amines by the phosphorus Mannich reaction. To determine if this reactivity can be used to synthesize phosphine macrocycles, trans-Fe(DHMPE)(2)Cl(2) (DHMPE = 1,2-bis(dihydroxymethylphosphino)ethane) was prepared and reacted with various amines. However, no phosphorus Mannich reactivity was observed. In order to unde...
متن کاملGreen Synthesis and Antihypertensive Activity of Some Mannich Bases of 1, 4 Dihydropyridine Compounds
Some new Mannich Bases of 1, 4 Dihydropyridine derivatives were synthesised by reaction of 1, 4 Dihydropyridine derivatives formaldehyde (HCHO) & secondary amines (e.g. morpholine, 1-methyl piperazine) in 1:1 ratio under acidic condition in presence of trace HCl. The compounds synthesised were identified by UV, 1H NMR, and FT-IR spectroscopic techniques. All compounds studied in this work were ...
متن کاملOrganocatalysed asymmetric Mannich reactions.
The asymmetric Mannich reaction ranks among the most potent enantioselective and diastereoselective C-C-bond forming reactions. In recent years, organocatalysed versions of asymmetric Mannich processes have been increasingly reported and used in a rapidly growing number of applications. This tutorial review provides an overview of the recent history of the asymmetric organocatalysed Mannich rea...
متن کاملReversible luminescent reaction of amines with copper(I) cyanide.
Copper(i) cyanide exposed to various liquid or vapor-phase amines (L) at ambient temperature produces a variety of visible photoluminescence colors via reversible formation of amine adducts. The adducts show phase matches to authentic (CuCN)L(n), n = 0.75-2.0, produced by heating CuCN with liquid amine.
متن کاملReversible luminescent reaction of amines with copper(I) cyanidew
One of the significant on-going challenges in chemistry is the specific and convenient detection of compounds of interest in the environment. Detection of volatile organic compounds (VOCs) via chemical ‘‘sniffing’’ requires an interaction between the VOC and a detector substrate, resulting in a measurable change. Crystal inclusion of VOCs into various d and d metal complexes has been found to a...
