Triphenylphosphine monomethylborane adduct, also known as (C6H5)3PCH3BH3, is a chemical compound formed by the combination of triphenylphosphine (PPh3) and monomethylborane (CH3BH3). This adduct is a colorless, crystalline solid that is soluble in organic solvents and is widely used as a reducing agent in organic synthesis. It is particularly effective in the reduction of carbonyl compounds, such as aldehydes and ketones, to their corresponding alcohols. The compound is also known for its ability to stabilize transition metal complexes and is used in the synthesis of various organoborane compounds. Due to its reactivity and reducing properties, it is essential to handle triphenylphosphine monomethylborane adduct with care, typically under an inert atmosphere to prevent unwanted side reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 79840-24-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,8,4 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 79840-24:
(7*7)+(6*9)+(5*8)+(4*4)+(3*0)+(2*2)+(1*4)=167
167 % 10 = 7
So 79840-24-7 is a valid CAS Registry Number.

Bestmann, Hans Juergen,Roeder, Thomas,Suehs, Kurt

, p. 1509 - 1518 (2007/10/02)

Triphenylphosphonium ylides 1 add borane (from 2) with formation of alkylidenetriphenylphosphorane-boranes 3, which rearrange on heating to give the triphenylphosphane-monoalkylborane adducts 6.Compounds 6 can undergo hydroboration reactions.
