    摘要: Disclosed is a process for forming a 1H-pyrazolo (1,5-b)-[1,2,4]-triazole compound by ring closing a pyrazoloamidine compound comprising reacting the amidine with an oxidizing agent having a reduction potential vs Ag/AgCl that is more positive than −0.16V and less than +1.43V in the presence of a halogen atom. The invention also discloses certain triazole compounds that are successfully made by the conventional process. The process and compounds of the invention provide improved yields and reduce or eliminate unwanted side-reactions.

    摘要: To assist transfer of toner images from a first transfer surface to a second transfer surface, the first transfer surface is actively cooled to prevent the toner sticking to it. Preferably, the cooling is accomplished by thermoelectric control device strips positioned in heat conducting relation with the first transfer surface. A thermoelectric control device can also be used to heat a second or receiving surface to which the toner is to be transferred to farther assist the transfer process.
