| titleOfInvention | A method of producing chalcogenopentalene compounds, electrophotographic compositions and elements containing these compounds, and novel tellurapentalene compounds |
| abstract | Chalcogenopentalene compounds of the general formula 1:n wherein n is 0 or 2; X and Z each independently represent O, NR or S; Y is Se or Te; W is halogen; R is hydrogen, substituted or unsubstituted alkyl or substituted or unsubstituted aryl; R 1 , R 2 , R 3 and R 4 each independently represent hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted aryl, substituted vinyl (R 5 CH=CH-) or halogen; and R 5 is substituted or unsubstituted or unsubstituted alkyl, substituted or unsubstituted aryl or a hetero group; provided that when Y is Se, R 1 , R 2 , R 3 and R. are other than halogen and n is 0, are useful in improving the sensitivity of electrophotographic compositions and elements. A method of making these compounds is provided. The tellurapentalenes are novel compounds. |
