Violent reaction with aluminum isopropoxide -f- heavy metal salts charcoal coal dimethylphenylphosphine hydrogen selenide lithium tetrahydroaluminate metals (e.g., potassium, sodium, lithium) metal oxides (e.g., cobalt oxide, iron oxide, lead oxide, lead hydroxide, manganese oxide, mercur oxide, nickel oxide) metal salts (e.g., calcium permanganate) methanol + phosphoric acid 4-methyl-2,4,6-triazatricyclo [5.2.2.0 ] undeca-8-ene-3,5-dione + potassium hydroxide a-phenylselenoketones phosphorus phosphorus (V) oxide tin(II) chloride unsaturated organic compounds. 

The principles of forming furan polymers from the condensation of furfuryl alcohol have become attractive for modifying wood, when ways of controlling the polymerization in dilute systems were discovered. There are several competing reactions condensation and cross-linking reactions of furfuryl alcohol with itself and also the reaction between furfuryl alcohol and lignin units is supposed (Scheme 9.4.10). ...

Reaction or the procyanidins with formaldehyde proceeds so rapidly that these products are usually not useful as wood adhesives. Herrick and Bock (153) advocate crosslinking these compounds with methylol-phenols rather than aldehydes. To gain further information about these reactions, both catechin and tetra-O-methyl catechin have been reacted with p- and o-hydroxybenzyl alcohol (142, 247). Reactions of catechin with /7-hydroxybenzyl alcohol gave the C-6, C-8, and C-6 + C-8 disubstituted products in approximately equal mole ratios. With o-hydroxybenzyl alcohol, substitution at C-8 was favored, with approximate yield ratios of 1 2.5 1.7, respectively. Foo and Hemingway (105) have also examined the regioselectivity of reactions of catechin with furfuryl alcohol and have obtained 2-furyl-(6-catechinyl)-methane and 2-furyl-(8-catechinyl)-methane in approximate relative yields of 1 2.7.
