Stannane, tetrakis(2-methylphenyl)-, also known as tetrakis(o-tolyl)stannane or 2-methylphenylstannane, is a chemical compound with the molecular formula C20H24Sn. It is a colorless, crystalline solid that is soluble in organic solvents. This organotin compound is characterized by a central tin atom bonded to four 2-methylphenyl (o-tolyl) groups. It is primarily used as a catalyst in various organic reactions, such as the Stille coupling, a type of cross-coupling reaction in organic chemistry. Due to its potential toxicity and environmental impact, it is important to handle Stannane, tetrakis(2-methylphenyl)- with care and in accordance with proper safety guidelines.

5728-01-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5728-01-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,2 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5728-01:
(6*5)+(5*7)+(4*2)+(3*8)+(2*0)+(1*1)=98
98 % 10 = 8
So 5728-01-8 is a valid CAS Registry Number.

The title compounds have been synthesized Grignard reactions or pyrolysis of diplumbanes respectively.The crystal structures of m-Tol4Pb and Ph4Pb (redetermination) have been determined.All eight compounds (Ph/Tol)4(Sn/Pb) are S4 symmetric and contracted along this unique axis.The 13C-NMR chemical shifts and the couplings 1J(119Sn/207Pb-13C) as well depend additively upon the methyl substituents.The ratios 1K(207Pb-13C):1K(119Sn-13C) of the reduced coupling constants are all near to 1.61; a comparison with values from the literature for alkyl, alkenyl and alkinyl substituents is given.The ratio δ(207Pb):δ(119Sn) results in 2.28.IR (700 down to 200 cm-1) and Raman (700 down to 50 cm-1) data are given.Key words: Tin; Lead; Group 14; Vibrational data; Nuclear magnetic resonance; Crystal structure
