Abstract: PURPOSE:To easily and directly obtain a 2-(disubstituted methylens)-1,3-dithiol in an economically advantageous way from a 1,3-dithiol-2-thione compound. CONSTITUTION:The compound of formula II can advantageously be obtained by reaction of (A) a compound of formula I (R and R are each H or inert substituent, or may form a ring through mutual binding of their terminals) with (B) a compound of formula R -CH2-R (R and R are each electron- accepting group) in the presence of (C) a silver salt, e.g. an organic carboxylic acid silver salt such as silver benzoate or silver acetate, or an inorganic silver salt such as silver nitrate, silver tetrafluoroborate or silver perchlorate, esp. a fluorine-contg. organic carboxylic acid silver salt such as CF3COOAg and (D) a base, pref. a tertiary amine, pref. in an anhydrous solvent at 0-150 (pref. room temperature to 80) deg.C. The amounts of the components to be used are as follows: B=1-2mol, C=1-5mol (each per mol of A); D=2-10mol per mol of B.

Abstract: PURPOSE:To perform measurement superior in reproducibility by providing a measuring part and a stage and arranging the measuring part at least in the vicinity of the stage. CONSTITUTION:A measuring part 22 and a stage 1 which holds the measuring part 22 and is made of a good heat conductor are provided, and the measuring part 22 is arranged at least in the vicinity of the stage 1. A sample attaching part which elastically presses plural terminals 6 for power supply and taking-out of a detection signal to a sample 2 to fix the sample 2 and a connecting means which connects terminals 6 and a measuring circuit are provided, and the stage 1 is provided with a temperature control means which keeps the stage 1 at a prescribed temperature. Ohmic contact to obtain a linear voltage-current characteristic is obtained at the time of connection between the sample and an electrode, and measured results superior in reproducibility are obtained. Further, the sample 2 generated in vacuum like a vapor-deposited film is measured without being taken out from the vacuum.
