Rutile TiO2 pigments codoped with chromophore ion Cr3+ and various charge-balancing ions (i.e., counterions species of Sb, Nb, W and Mo) were prepared by a solid-phase reaction method. The effects of the counterions and calcination temperatures on th

The synthesis of quadrupolar tetraphenyl- carbo -benzene derivatives is envisioned through the corresponding tetraphenyl-tetramethoxy-[6]pericyclynedione last-but-one precursor. The latter was thus prepared in 9 steps and 7% overall yield via the cor

Critical analysis of possible strategies for the synthesis of novel carbo-benzene derivatives suggests several [(18-n)+n] routes for the preparation of hexaoxy[6]pericyclyne precursors. Beyond the previously attempted [9+9] symmetrical scheme (n=9),
Stereoselective double addition of chiral alkynyl-zincs to cobalt-stabilized acetylenedicarbaldehyde

Acetylenedicarbaldehyde, a desirable but intractable C 4 synthon, can be protected as the Gorgues’ dicobalt hexacarbonyl complex. It undergoes chimio-, diastereo- and enantioselective attack of terminal alkynes using zinc triflate and (−)- N -met

The title journey is undertaken at the levels of both theory and experiment. Since 1983, homoaromaticity has been shown to play at most a minor role in the stability of Scott's [N]pericyclyne hydrocarbons - the first ring carbo-mers of cycloalkanes.

Reductive treatment of stereoisomeric mixtures of variously substituted hexaoxy[6]pericyclynes with SnCl(2)/HCl led to the corresponding substituted carbo-benzenes. Tetramethoxyhexaphenyl[6]pericylynediol and dimethoxyhexaphenyl[6]pericyclynetetrol t

Reduction of decyl dichloro- and trichloroacetate, under mild electrolysis conditions by using the sacrificial anode process, affords α-chlorocarbanions which readily react with trialkylboranes to give alkylated products in a one step reaction.

The total carbo-mer of benzene, hexaethynyl carbo-benzene C30H6, has been calculated at the B3PW91/6-31G** level. Its geometrical and magnetic characteristics are compared with those of the C18H6 partial carbo-mers, unsubstituted carbo-benzene, and h
