R. Richter et al., REACTION OF 1,1'-BIS(ALKYLAMINOMETHYLENE) FERROCENES WITH BENZOYLISOTHIOCYANATE, Journal of organometallic chemistry, 525(1-2), 1996, pp. 199-205
The reaction of 1,1'-bis((n)butylaminomethylene)ferrocene with two equ
ivalents of benzoyl isothiocyanate yields errocenediyl-bis(N-methylene
-N-(n)butyl-N'-benzoyl thiourea). In contrast, the respective reaction
with 1,1'-bis(ethylaminomethylene)ferrocene leads to 2-N-ethylammoniu
m-[3]-1,1'-ferrocenophane thiocyanate. Both compounds are characterize
d by X-ray structure determination. A possible reaction mechanism is d
iscussed.
