Preparation and chemistry of new unsymmetrically substituted tetrachalcogenofulvalenes bearing CN(CH2)2X and HO(CH2)2X groups (X = S or Se)

Several unsymmetrically substituted TTFs bearing the S(CH2)2CN protecting group have been prepared by standard cross coupling in triethyl phosphite from the key intermediate 4,5-bis(2′-cyanqethylsulfanyl)-1,3-dithiol-2-one 1 and an a

Synthesis of unsimmetrically substituted tetrathiafulvalenes by the "ylid route". Investigations of selectivity.

The selective synthesis of unsimmetrically substituted tetrathiafulvalenes 1 (R R') using phosphonium ylids 2 and dithiolium salts 3 in THF at -80 deg C has been investigated.Several unsymmetrical tetrathiafulvalenes were obtained in good yield. R,R'=CH3; (CH2)4; o-C6H4.It was also shown that the instability of the phosphonium ylid 2 and dithiolylium 3 under the rreaction conditions leads to the formation of variable amounts of symmetrical terathiafulvalenes 1 (R = R').Therefore, purification of the mixture by column chromatography with CS2 as eluent was necessary.

INSERTION OF 1,3-DITHIOLIUM CARBENES INTO N-H BOND OF AMIDES AND IMIDES

It was found that 1,3-dithiolium carbenes (4a-d) generated from 2-methoxy-1,3-dithioles (1a-d) were inserted into N-H bond of N-methylbenzamide, acetanilide and succinimide to form N-(1,3-dithiol-2-yl)amides (imides) 8-10, respectively.It was shown that N
