| Abstract | The reaction of flavanone with Cr(CO)6 gives two diastereomeric complexes 1 (cis) and 2 (trans) with the general formula [Cr(CO)3(C15H12O2)]. Due to the existence of an asymmetric carbon atom in the γ-pyrone ring, the two isomers are chiral. Both complexes were characterized by elemental microanalysis as well as by IR, NMR, UV, and mass spectroscopy. The X-ray analysis of 1 has shown that the Cr(CO)3 tripod is complexed to the benzene ring in an eclipsed conformation. The phenyl group adopts a cis configuration with respect to the tricarbonylchromium moiety, and the γ-pyrone ring is oriented in a 1,2-diplanar conformation. Die Umsetzung von Flavanon mit Cr(CO)6 ergibt zwei diastereomere Komplexe 1 und 2 der allgemeinen Formel [Cr(CO)3(C15H12O2)]. Wegen des asymmetrischen Kohlenstoffatoms im γ-Pyronring sind die beiden Isomeren chiral. Beide Komplexe wurden elementaranalytisch sowie IR-, NMR-, UV- und massenspektroskopisch charakterisiert. Die Röntgenstrukturanalyse von 1 zeigt, daßder Cr(CO)3-Dreifuß bezüglich des Benzolrings ekliptisch orientiert ist. Die Phenylgruppe ist relativ zur Tricarbonylchromkomponente cis-konfiguriert, während der γ-Pyronring eine 1,2-diplanare Konformation einnimmt. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
