A combination of Pd(dba)2-PPh3-CuI-LiCl or Pd(dba)2-P(2-furyl)3-CuI-LiCl effectively catalyzed the cross-coupling of (Z)-germyl(stannyl)ethenes with aryl halides, providing novel triethyl(2,2-diphenylethenyl)germanes in good to high yields. The reaction proceeds with retention of configuration. | |

A new series of chiral 3-hydro-xyazetidines has been prepared from (S)-1-(4-methoxyphenyl)ethylamine. They have excellent catalytic activities and enantiomeric selectivities in asymmetric addition of diethylzinc to aromatic aldehydes. | |
AACVD of WO3 thin films from W(O)(OPri)3[O(CH2)nNMe2] (n = 2, 3) (p 676-683)

Monomeric tungsten oxo-aminoalkoxides W(O)(OPri)3(L) [L = O (CH2)nNMe2; n = 2 (dmae, 1) and 3 (dmap, 2)] were synthesized and, along with [W(O)(OPri)4]2 (3), used as precursors for the aerosol-assisted chemical vapour deposition of WO3 thin films. A rough, amorphous film grown from 3 showed better solar control properties than dense, crystalline films produced from 2 and 3. | |
Oxygenation of aromatic hydrocarbons with hydrogen peroxide catalyzed by rhodium carbonyl complexes (p 684-688)

Cluster Rh6(CO)16, as well as certain other rhodium carbonyl complexes, catalyze benzene hydroxylation with hydrogen peroxide in acetonitrile solution. Phenol and (in less concentration) quinone are formed with the maximum attained yield and turnover number 17% and 683, respectively. | |

Phenolic resin was synthesized by polycondensation of phenolic derivatives of benzophenone with 1,4-butane diol in acidic medium. The resin formed polychelates with inner transition metal ions, as shown in the figure. Polychelates were found to be an efficient catalyst in organic synthesis and good antimicrobial agents against different microorganisms. | |
A novel approach to consolidation of historical limestone: the calcium alkoxides (p 698-704)

Utilization of calcium alkoxides as stone consolidants has been investigated. Reaction of Ca(OR)2 with the atmosphere produces CaCO3 in the form of vaterite and calcite. Impregnation of a porous substrate, simulating the deteriorated stone, with a methanol solution of Ca(OCH3)2, produces a crystalline vaterite film, which gradually fills all the pores and cavities of the substrate fulfilling the necessary requirements a consolidant should have. | |
Solvent-free synthesis of 
-aminonitriles from aldehydes, amines and trimethylsilyl cyanide catalyzed by thallium(III) chloride tetrahydrate (p 705-711)
