Application

Tin(II) chloride dihydrate can be used as a mild Lewis acid catalyst to synthesize:      
  • 3-Aminoimidazo[1,2-a]pyridines via three-component condensation reaction of aromatic aldehydes, 2-aminopyridines, and isonitriles.     
  • Pyrazolo[5,4-b]quinoline derivatives via cyclocondensation reaction of 5-amino-3-(arylamino)-1H-pyrazole-4-carbonitriles with cyclohexane-1,3-dione or dimedone.    
  • Polylactic acid from aqueous lactic acid in the presence of succinic anhydride.

It can also be used as a cocatalyst to synthesize indole derivatives by treating anilines with trialkanolamines in the presence of ruthenium as a catalyst.

Continuously enhanced photoresponsivity and suppressed dark/noise current combinatorially lead to the recent development of high-detectivity organic photodetectors with broadband sensing competence. Despite the achievements, reliable photosensing enabled by organic photodetectors (OPDs) still faces challenges. Herein, we call for heed over

Tin oxide (SnO2) is widely adopted as an electron transport layer in perovskite solar cells (PeSCs) because it has high electron mobility, excellent charge selective behavior owing to a large band gap of 3.76 eV, and low-temperature processibility. To achieve

[reaction: see text] Under the Lewis acid catalysis offered by TiCl(3), SnCl(2) can efficiently mediate the aqueous Barbier reactions between aldehydes and allyl chloride or bromide.

Condensations between the tin(II) enolate 11 of ethyl N-tosylglycinate and conjugated ynals 12 and ynones 14 are highly diastereoselective, in favour of the anti-isomers 13 and 15; similar reactions of enals and enones 17 show lower but still useful levels
