In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Catalytic transformation of silicon tetraisocyanate Si(NCO)4 to a polymeric silylcarbodiimide, published in 2013, which mentions a compound: 707-61-9, Name is 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide, Molecular C11H13OP, Formula: C11H13OP.
A new way for the preparation of inorganic polymeric carbodiimide-based networks is presented which resembles the transformation of mol. isocyanates using 1-phenyl-3-methyl-2-phospholene-1-oxide as a catalyst. The resp. reaction sequence, well established in preparative organic chem., has been applied for the synthesis of carbodiimide-based SiNC(O) materials. Starting from Si(NCO)4 (silicon tetraisocyanate), a transformation to an insoluble extended inorganic array was achieved in boiling dodecane (T = 216 °C). Anal. of the polymer using X-ray diffraction, FT-IR, d. measurement, matrix-assisted laser desorption/ionization time of flight and TGA revealed that this highly moisture-sensitive amorphous network consists of oligomers of high molar mass and exhibits a high d. of around 1.5 g.cm-3, which corresponds quite well to the calculated d. of crystalline Si(NCN)2 reported in the literature. Degradation of this ‘SiNC(O) phase’ with the release of N2 and (CN)2 finally provided SiC as the only crystalline product. No indication of the formation of crystalline Si3N4 or intermediate crystalline ‘SiC2N4’, silicon carbodiimide (= Si(NCN)2), was noticed. Copyright © 2012 John Wiley & Sons, Ltd.
