Some less hindered 2,4,6-tri-aryloxy-s-triazines were synthesized through the reaction of the corresponding phenols as a starting materials with cyanogen bromide (BrCN) to obtain the corresponding arylcyanates and then trimerized. Unexpectedly, 2,4-di-tert-butyl-1-cyanatobenzene derived from 2,4-di-tert-butylphenol did not trimerize but, indeed, yielded bis(2,4-di-tert-butylphenyl) carbonate. The structures of 2,4,6-tri-aryloxy-s-triazines and bis(2,4-di-tert-butylphenyl) carbonate were characterized by means of IR, 1H, and 13C NMR spectroscopies. Also the structure of the latter compound was studied by X-ray crystallography.

A novel reactive polymer containing cyanate groups in the side chain was prepared by free radical polymerization of a cyanate-containing monomer, 2-(4-cyanatophenyl)ethyl methacrylate (1). The monomer 1 and its polymer, poly[2-(4-cyanatophenyl)ethyl methacrylate] (PCPMA), were stable under the air for a long period. The copolymerization of 1 and methyl methacrylate provided the corresponding copolymers with various cyanate contents. The availability of the cyanate-containing polymers as a reactive polymer was investigated. Model reaction using 4-cyanatotoluene revealed that a cyanate group reacted with aliphatic amines, whereas no reaction occurred in the presence of water, alcohols, and aromatic amines under mild conditions. Post-functionalization of PCPMA was demonstrated using aliphatic amines or diamines. Copyright

Seven new substituted 5-phenoxy-1,2,4-dithiazole-3-ones were prepared in modest yield (53-76%) from corresponding O-phenyl thiocarbamates and chlorocarbonylsulfenyl chloride in dry ether at-10 °C. All of the compounds were characterized by NMR and elemental analysis and some of them by X-ray diffraction. Preliminary kinetic measurements showed that the parent 5-phenoxy-1,2,4-dithiazole-3-one is a very efficient sulfurizing agent toward triphenyl phosphite. Copyright
Interaction of aryloxychlorocarbenes with acetylenedicarboxylate: Novel formation of polyfunctional butadienes and 8-oxatricyclo[3.2.1.0 2.4]oct-6-enes

The interaction of aryloxychlorocarbenes with dialkyl acetylenedicarboxylates has been examined. Thermolyses of 3-aryloxy-3- chlorodiazirines in the presence of acetylenedicarboxylate resulted in the formation of unexpected polyfunctional 1,3-butadienes and 8-oxatricyclo[3.2.1. 02.4]oct-6-enes or of 2-aryoxycarbonylmaleates dependent upon reaction conditions. This work confirmed the nucleophilicity of aryloxychlorocarbenes and underlined their synthetic potential.
Cyanic Acid Esters. 29. Bezoxazoline-thione-N-imid Esters and Their Consecutive Reactions

Oxazoline-thiones-(2) and aryl cyanates react to form the corresponding isoureas 4.These compounds are remarkably stable against electrophilic reagents.The aminolysis of 4 proceeds two pathwais: a transformation of the imid ester residue to the amin and a ring opening reaction by attack of the amin to the C=S-bond.The hydrazinolysis causes a ring-transformation of the oxazoline- to the 1,3,4-triazole systems.
