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. 

OXALIC ACID (144-62-7) CjHjO. HOOCCOOH Combustible solid heat-sensitive. (combustible <215 F/101°C. Fire Rating 1). Exposure to elevated temperatures, hot surfaces, or flames causes decomposition and the formation of toxic and flammable formic acid and carbon monoxide. Hygroscopic the solution in water is a medium-strong acid. Violent reaction with strong oxidizers, acid chlorides alkali metals bromine, furfuryl alcohol hydrogen peroxide (90%) phosphorus trichloride silver powders sodium, sodium chlorite sodium hypochlorite urea + heat (forms NHj gas, CO2 and CO may explode). Mixture with some silver compounds forms explosive salts of silver oxalate. Incompatible with caustics, mercury, urea. On small fires, use dry chemical powder (such as Purple-K-... 

SUBCHLORIDE of MERCURY (10112-91-1 7546-30-7) see mercurous chloride. SUBERANE (291-64-5) see cycloheptane. SUCCINIC ACID (110-15-6) C4HSO4 Combustible solid. Dust or powder may form explosive mixture with air. Violent reaction with strong acids, strong oxidizers. Decomposes in elevated temperatures above 455°F/235°C, forming succinic anhydride. Violent reaction with all bases (exothermic reaction) including amines, amides, and inorganic hydroxides strong oxidizers, furfuryl alcohol (explosion), hypochlorites, isocyanides, nitromethane, chromic acid. 

Some of the typical conditions of polycondensations used for aliphatic and aromatic monomers are not suitable for furan derivatives, e.g., the melt polycondensation of 2,5-furan dicarboxylic acid chloride with 2,5-b/s(hydroxymethyl) furan at about 80 °C only yields a black insoluble product5. The hydrochloric acid liberated in the reaction is clearly responsible for the charring of the furanic diol which like its simpler homologue furfuryl alcohol, resinifies rapidly in acidic media (see below). 

Reaction of 56 with thiols in dichloromethane gives the analogous alkyl-thiomethyl and cycloalkylthiomethyl derivatives [e.g., treatment with ethanethiol gives A -(2-hydroxyethylthiomethyl)vinblastine (57)] (75). Compound 56 is also a useful intermediate for the preparation of N-1-furanyl derivatives. For example, treatment of 56 with furfuryl alcohol in methylene chloride in the presence of trace acid gives N -[(5-hydroxy-methyOfurfuryl]vinblastine (58). 

However, the most important furan resins are those produced with 2-furfuryl alcohol, for example, the 2-furfuryl alcohol-formaldehyde-based resins, which are normally synthesized by a condensation reaction catalyzed by acidic sites and promoted by heat [224] or the poly(furfuryl alcohol) thermosetting resin that is usually synthesized by the cationic condensation of its monomer 2-furfuryl alcohol, which polymerizes exothermically in the presence of a catalyst such as acid and iodine in methylene chloride, producing black, amorphous, and branched and/or cross-linked structures [225],... 

The Diels-Alder reaction of ester-tethered trienes is also known as a powerful methodology to construct polycylic Y lactones [68]. Romo et al. [69] surveyed effective organic nucleophilic catalysts for tandem intermolecular Diels-Alder reaction/lactonization reaction of achiral a, 3-unsaturated acid chlorides with dienyl alcohol 100 (Scheme 45). In this case, when chiral Lewis base 102 was used as a nucleophilic catalyst, excellent enantioselectivity was realized. Lipase-catalyzed domino kinetic resolution/intramolecular Diels-Alder reaction of furfuryl alcohols with acrylic acids was also carried out by Akai and Kita [70].
