Preparation and spectroscopic study of functionally substituted cyclopentadienides of thallium(I), potassium, rhodium(I), and iridium(I) was written by Arthurs, Michael;Al-Daffaee, Hafid K.;Haslop, John;Kubal, Gina;Pearson, Matthew D.;Thatcher, Peter;Curzon, Eirian. And the article was included in Journal of the Chemical Society, Dalton Transactions: Inorganic Chemistry (1972-1999) in 1987.Category: chlorides-buliding-blocks This article mentions the following:
The different patterns observed for the ring nuclei in 13C and 1H NMR study of a series of monosubstituted cyclopentadienide compounds of type M(C5H4X) [M = K, Tl; X = Cl, COMe, CO2Me, CHO, Ph, COCO2Et, C(CN):C(CN)2] reflect both the Lewis acid character of the metal and the electronic effect of the substituent. Fluxional behavior is observed for K(C5H4COMe). Pseudo-first-order rate constants have been evaluated for H-D exchange in several of the K compounds The Th(I) compounds generally exhibit greater synthetic utility than their K analogs and several have been used in the synthesis of new [M(畏5-C5H4X)(畏2-C2H4)2] (M = Rh, Ir) complexes. Activation barriers for alkene rotation and mass spectral fragmentation patterns are discussed for these compounds The 1H NMR spectra for the cyclopentadienyl ring indicate that the M-ring bonding is not fully delocalized. Anal. of the products resulting from reaction between ClCO2Me and K(C5H5) confirm the strongly electrophilic character of the former reagent. In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Category: chlorides-buliding-blocks).
Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Category: chlorides-buliding-blocks
