Triaryl- and triheteroarylmethanes have been synthesized in very good yield under solvent-free conditions from differently substituted aldehydes and 2-methylfuran or methoxybenzene in the presence of Yb(OTf)3 as catalyst. Wiley-VCH Verlag GmbH & Co. KGaA, 2009.

Alkylation of heteroarenes by using aldehydes is a direct approach to increase molecular complexity, which however often involves the use of stochiometric oxidant, strong acid, and high temperature. This study concerns an energy-efficient electrochemical alkylation of heteroarenes by using aldehydes under mild conditions without mediators. Interestingly, the graphite anode can trigger aldehyde cationic species, which act as the effective autocatalysts to react with a range of heteroarenes to produce the corresponding products with excellent regioselectivity and in high yields. Compared to the traditional electro-synthesis approaches, this electro-triggered reaction provides an electricity-saving and eco-friendly route to high-value chemicals.
Cu(OTf)2 catalyzed synthesis of bis(5-methyl-2-furyl)methanes by condensation of 2-methylfuran with carbonyl compounds under solvent free conditions

experimental part, p. 1483 - 1488 (2011/10/31)
A facile and efficient one-pot three-component synthesis of bis(5-methyl-2-furyl)methanes has been achieved via the reaction of 2-methylfuran with a series of aliphatic and aromatic aldehydes and aliphatic ketones in presence of copper(II) triflate under solvent free conditions. The bis(5-methyl-2-furyl)methanes were obtained in 34%-72% yields and the catalyst was recycled up to four successive cycles without much loss in catalytic activity. Copyright
Complexes of titanium(IV) chloride with N-(3,5-R,R′-salicylidene)- 2(3,4)-[bis(5-methyl-2-furyl)methyl]aniline, a novel type of phenoxyimine catalysts for olefin polymerization

New representatives of chelate-type titanium(IV) salicylideneaniline complexes with bis(5-methyl-2-furyl)methyl substituents in the aniline fragment are synthesized. In the presence of poly(methylalumoxane), these complexes catalyze ethylene and propylene polymerization. The effect of the position of substituents in the ligands on the activities of the catalysts is studied. High-molecular-weight linear polyethylene (M w ≈ 172200-300000, M w/M n ≈ 2-3) and high-molecular-weight atactic elastic polypropylene (M w ≈ 1000000, M w/M n ≥ 7.0) are obtained.
POLYFURYL(ARYL)ALKANES AND THEIR DERIVATIVES. 3. SYNTHESIS OF DERIVATIVES OF DIFURYLPHENYL- AND TRIFURYLMETHANE
Zhuravlev, S. V.,Kul'nevich, V. G.
, p. 478 - 481 (2007/10/02)
Previously unknown difurylphenyl- and trifurylmethanes were obtained by the reaction of aromatic aldehydes with furan derivatives in benzene in the presence of perchloric acid.
