The first catalytic use of Ga(0) in organic synthesis has been developed by using a Ag(I) cocatalyst, crownether ligation, and ultrasonic activation. Ga(I)-catalyzed C-C bond formations between allyl or allenyl boronic esters and acetals, ketals, or aminals have proceeded in high yields with essentially complete regio- and chemoselectivity. NMR spectroscopic analyses have revealed novel transient Ga(I) catalytic species, formed in situ through partial oxidation of Ga(0) and B-Ga transmetalation, respectively. The possibility of asymmetric Ga(I) catalysis has been demonstrated.

We have used SBA-15 silicas as hard templates for the nano-fabrication of Cs1.8H2.2SiW12O40 (CsHSiW) salt nanocrystal. The elimination by HF (or NaOH 90 °C) in the silica matrix from the composites occurred by a

The electrochemical cyclization of a series of ortho-halo-substituted homoallyl ethers and esters to functionalized indanes catalyzed by Ni(II) catalyst precursors derived from Ni(cyclam)Br2, (cyclam = 1,4,8,11-tetraazacyclotetradecane) and Ni(tmc)Br2, (tmc = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) is reported. The starting homoallyl ethers were synthesized using either a one-pot method for allylation of aldehydes or by direct allylation of the corresponding acetals using bismuth triflate as a catalyst. The remarkably low toxicity, low cost and ease of handling of bismuth salts coupled with the mild nature of the electrochemical procedure makes this approach to indane synthesis especially environmentally friendly and attractive.
