Manganese-catalyzed carbonylation of alkyl iodides
… for the manganese-catalyzed carbonylation of alkyl iodides while using a variety of nucleophiles was developed. The method concerns the alkoxy and amino carbonylation as well as the use of more unconventional nucleophiles such as thiols, azide and hydride. The method employs alkyl iodides …

Ionene and ionene alkyl sulfate stoichiometric complexes
… formed stoichiometric complexes with alkyl sulfates. The ionene alkyl sulfate complexes display mesogenicity, i.e. optically isotropic dry complexes underwent lyotropic and thermotropic phase transitions to the optically anisotropic phase (and vice versa) under controlled relative …

Alkyl, alkenyl and cycloalkyl substituted triphenylmethane dyes
… series of Malachite Green derivatives containing alkyl an alkenyl substituents in the 2-, 3-. and 4- positions has been synthesised. Their respective visible absorption spectra have been correlated with the electronic and steric effects of the methyl, ethyl, propyl, butyl and vinyl substituents in …

Early Transition Metal Alkyl and Tetrahydroborate Complexes
An investigation of early transition metal alkyl and tetrahydroborate complexes as catalytic models and ceramic precursors has been initiated. The compounds MX$\sb2$ (dmpe)$\sb2$, dmpe = 1,2-bis(dimethylphosphino)ethane, for M = Ti, V, Cr, and X = Br, I, BH$\sb4$, have been prepared. These …

Cross-coupling reactions of unactivated alkyl halides
… cross-coupling reactions using unactivated alkyl electrophiles (e.g., halides and sulfonates). Although aryl and alkenyl electrophiles have been commonly used in such processes, the utility of alkyl substrates has been underdeveloped, and merits further exploration. We have developed the …
