Ethynyl(trimethyl)stannane, also known as trimethyl(ethynyl)stannane or methylacetylenetin, is an organotin compound with the chemical formula C5H10Sn. It is a colorless liquid that is sensitive to air and moisture. ethynyl(trimethyl)stannane is characterized by a tin atom bonded to three methyl groups and an ethynyl (acetylene) group. Ethynyl(trimethyl)stannane is used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Stille coupling reaction, a type of cross-coupling reaction in which an organotin compound reacts with an organohalide in the presence of a palladium catalyst. It is also employed in the synthesis of various organotin compounds and as a precursor in the production of certain polymers and materials. Due to its reactivity and potential health hazards, it is important to handle ethynyl(trimethyl)stannane with care, using appropriate safety measures.

1112-00-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1112-00-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,1 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1112-00:
(6*1)+(5*1)+(4*1)+(3*2)+(2*0)+(1*0)=21
21 % 10 = 1
So 1112-00-1 is a valid CAS Registry Number.

Alkynyl-siibstituted tricarbonyl(cyclobutadlene)iron complexes: coupling of complexes sfannylalkynes

Bunz, Uwe H. F.,Jutta

, p. 785 - 797 (2007/10/03)

The synthesis of mono-, di-, tri- and tetraalkynylated tricartaonyl(cyclobutadiene)iron complexes is accomplished by a repetitive metalation/iodination/coupling sequence. Application of this sequence leads to the synthesis of oligomeric cyclobutadiene complexes with various topologies, inter alia to the synthesis of a perethynylated aimer 24. Alternatively a one-step coupling procedure (Stille-Farina) has been used to synthesize tetraalkynylated tricarbonyl(cyclobutadiene)irons 26, VCH Verlagsgesellschaft mbH, : 1996.
