Abstract
Background:
Four members of N,N-disulfo-1,1,3,3-tetramethylguanidinium chlorometallates [DSTMG]n[X],
where n= 1 or 2; X= FeCl4
-
, Zn2Cl6
2-, NiCl4
2-, MnCl4
2- were synthesized as solid Brønsted-Lewis acidic compounds and
studied the catalytic activity with the most acidic salt for three-component synthesis of 1,2-dihydro-1-aryl-3H-naphth[1,2-
e][1,3]oxazin-3-ones.
Methods:
N,N-disulfo-1,1,3,3-tetramethylguanidinium chlorometallates of the four transition metal cations such as
Fe(III), Zn(II), Ni(II) and Mn(II) were prepared after treatment of the parent ionic liquid N,N-disulfo-1,1,3,3-
tetramethylguanidinium chloride [DSTMG][Cl] with the respective metal chlorides in different mole fractions at 75 ºC.
The synthesis of 1,2-dihydro-1-aryl-3H-naphth[1,2-e][1,3]oxazin-3-ones was carried out via three-component reaction of
2-naphthol, aromatic aldehydes and urea under neat condition at 90 ºC using 7 mol% of the [DSTMG][FeCl4] catalyst.
Results:
The characterization of synthesized chlorometallates were done using spectroscopic and other analytical techniques including thermogravimetric analysis and Hammett acidity studies. Among the four salts, the salt of Fe(III) ion was
observed as the strong Brønsted acidic hydrophobic salt and thus chosen for the catalytic study.
Conclusion:
A new type of chlorometallates of guanidinium cation with composition [DSTMG]n[X], where X= FeCl4
-
/Zn2Cl6
2-/ NiCl4
2-/ MnCl4
2- and n= 1 or 2 were developed as –SO3H functionalized solid acids with varied thermal stability
(150-250 ºC) and physisorbed water (0-20%) as observed from the thermogravimetric study. From them, the most
Brønsted acidic Fe(III) salt was employed as efficient recyclable heterogeneous catalyst for the one-pot synthesis of 1,2-
dihydro-1-aryl-3H-naphth[1,2-e][1,3]oxazin-3-ones in neat condition.

Abstract
A novel heterogeneous silica nanosphere-supported ferrocene-containing ionic liquid catalyst (SiO2@Imid-Cl@Fc) was designed and synthesised and was systematically characterised by Fourier transform infrared (FTIR) spectroscopy, field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray (EDX) and X-ray diffraction (XRD) analysis. The catalytic activity of the SiO2@Imid-Cl@Fc catalyst was tested in a one-pot, three-component reaction of malononitrile and kojic acid with 15 aromatic aldehydes at room temperature under ultrasound irradiation. The products were pyrano[3,2-b]pyran derivatives, four of which are new. The catalyst exhibited good catalytic performance over short reaction times (15–20 min) and could be recycled at least five times without significant loss of activity.
