Trimethylsilylhypophosphite, also known as (trimethylsilyl)hypophosphorous acid or Me3SiHPO, is an organophosphorus compound characterized by the presence of a trimethylsilyl group (SiMe3) and a hypophosphite group (HPO). It is a colorless, volatile liquid with a pungent odor and is soluble in organic solvents. This chemical is primarily used as a reagent in organic synthesis, particularly for the reduction of various functional groups, such as carbonyl compounds, nitro groups, and azides. Trimethylsilylhypophosphite is also employed as a protecting group for alcohols and as a reducing agent in the preparation of phosphine ligands for transition metal catalysts. Due to its reactivity and potential hazards, it should be handled with care and stored under an inert atmosphere.

Check Digit Verification of cas no

The CAS Registry Mumber 38049-93-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,0,4 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 38049-93:
(7*3)+(6*8)+(5*0)+(4*4)+(3*9)+(2*9)+(1*3)=133
133 % 10 = 3
So 38049-93-3 is a valid CAS Registry Number.

Reaction of bis(trimethylsiloxy)phosphine with trimethylsilane

Voronkov,Pestunovich,Albanov,Kukhareva

experimental part, p. 1080 - 1082 (2011/05/04)

Bis(trimethylsilyl) [3-(trimethylsilyl)propyl]phosphonate and trimethylsilyl [3-(trimethylsilyl)propyl]-phosphinate are obtained by the reaction of bis(trimethylsiloxy)phosphine with trimethylallylsilane and converted into [3-(trimethylsilyl)propyl]phosphinic and [3-(trimethylsilyl) propyl]phosphonic acid, respectively, by the reaction with methanol.
