Phosphonic acid, (1-phenyl-1,2-propadienyl)-, diethyl ester, also known as diethyl (1-phenyl-1,2-propadienyl)phosphonate, is an organophosphorus compound with the chemical formula C11H13O2P. It is a colorless liquid with a molecular weight of 210.19 g/mol. Phosphonic acid, (1-phenyl-1,2-propadienyl)-, diethyl ester is characterized by the presence of a phosphonic acid group attached to a phenyl group and a 1,2-propadienyl group, with two ethyl ester groups bonded to the phosphorus atom. It is used as a reagent in organic synthesis, particularly in the preparation of various phosphorus-containing compounds and as a ligand in coordination chemistry. Due to its reactivity and potential toxicity, it is important to handle this chemical with care and in accordance with proper safety protocols.

3095-10-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3095-10-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,9 and 5 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3095-10:
(6*3)+(5*0)+(4*9)+(3*5)+(2*1)+(1*0)=71
71 % 10 = 1
So 3095-10-1 is a valid CAS Registry Number.

Palladium(0)-catalyzed highly regio- and stereoselective addition of organoboronic acids with 1,2-allenylphosphonates forming tri- or tetrasubstituted 1(E)-alkenylphosphonates

Ma, Shengming,Guo, Hao,Yu, Fei

, p. 6634 - 6636 (2006)

A highly regio- and stereoselective palladium(0)-catalyzed addition of organoboronic acids with 1,2-allenylphosphonates in the presence of HOAc forming tri- or tetrasubstituted 1(E)-alkenylphosphonates is reported in this paper. The stereoselectivity is m

Novel, stereoselective and stereospecific synthesis of allenylphosphonates and related compounds via palladium-catalyzed propargylic substitution

Kalek, Marcin,Stawinski, Jacek

supporting information; experimental part, p. 1741 - 1755 (2011/09/15)

We have developed a novel method for the synthesis of allenylphosphonates and related compounds based on a palladium(0)-catalyzed reaction of propargylic derivatives with H-phosphonate, H-phosphonothioate, H-phosphonoselenoate, and H-phosphinate esters. The reaction is stereoselective and stereospecific, and provides a convenient entry to a vast array of allenylphosphonates and their analogues with diverse substitution patterns in the allenic moiety and at the phosphorus center. Some mechanistic aspects of this new reaction were also investigated. Copyright
