Indenyl-functionalised BEt(3)-adduct NHCs were prepared by the reaction of imidazolium pro-ligands with LiBEt(3)H. This compound was converted into the indenyl-coordinate molybdenum complex dangling the NHC·BEt(3) moiety as a substituent. The stepwise coordination of NHC afforded a chelate-type mononuclear complex as well as a bimetallic complex.

Abstract Studtite is known to exist at the back-end of nuclear fuel cycle as an intermediate phase formed in reprocessing spent fuel. In thermal decomposition studtite, amorphous obtained calcination temperatures between 200 and 500 °C. This compound, referred elsewhere literature U 2 O 7 , has been characterised by analytical spectroscopic methods. The local structure compound found contain ur...

Bioinorganic medicinal chemistry remains a hot field for research aimed at developing novel anti-cancer treatments. Discovery of metal complexes as potent antitumor chemotherapeutics such as cisplatin led to a significant shift of focus toward organometallic/ bioinorganic compounds containing transition metals and their chelates as novel scaffolds for drug discovery. In that way, transition met...

Riboflavin synthase catalyses a mechanistically complex dismutation affording riboflavin and 5-amino-6-ribitylamino-2,4(1H,3H )-pyrimidinedione from 6,7-dimethyl-8-ribityllumazine. A pentacyclic adduct (compound 2 ) of two substrate molecules was used as substrate for pre-steady-state kinetic analysis. Whereas the wild-type enzyme catalyses the decomposition of compound 2 into a mixture of ribo...

When rabbit muscle phosphorylase reconstituted with pyridoxal (5’)-diphospho(l)-a-~-glucose is incubated with glycogen, its glucosyl moiety is transferred to the nonreducing end of glycogen with the formation of a new a-1,4-glucosidic linkage. This finding provided the first evidence for the direct phosphate-phosphate interaction between the coenzyme pyridoxal 5’phosphate and the substrate a-D-...

In an attempt to prepare the tris(selenoureato)gallium(III) complex [Ga(4-O2NC6H4C(O)NC(Se)NEt2)3] from the reaction of the nitro-substituted acylselenourea 4-O2NC6H4C(O)NHC(Se)NEt2 with [Ga(NO3)3] in EtOH we obtained a crystalline compound from a CH2Cl2 solution which was identified as the bis(selenoureato)gallium(III)chlorido complex [GaCl(4O2NC6H4C(O)NC(Se)NEt2)2] by single-crystal X-ray dif...
