1-Ethoxy-3,4-dimethyl-2,3-dihydro-1H-phosphole 1-oxide is a complex organic compound with the molecular formula C7H15OP. It is a derivative of phosphole, a heterocyclic compound containing a phosphorus atom in a five-membered ring. This specific compound features an ethoxy group (C2H5O) attached to the 1-position, and two methyl groups (CH3) at the 3 and 4 positions of the phosphole ring. The 1-oxide notation indicates the presence of an oxygen atom double-bonded to the phosphorus atom, which is characteristic of a phosphine oxide. 1-ethoxy-3,4-dimethyl-2,3-dihydro-1H-phosphole 1-oxide is of interest in organic chemistry and materials science, particularly in the synthesis of phosphorus-containing compounds and as a potential precursor for the development of new materials with unique properties.

Check Digit Verification of cas no

The CAS Registry Mumber 699-63-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 699-63:
(5*6)+(4*9)+(3*9)+(2*6)+(1*3)=108
108 % 10 = 8
So 699-63-8 is a valid CAS Registry Number.

The Reaction of 1-Substituted 3,4-Dimethyl-Δ3-phospholens with Diethyl Peroxide: a Correlation Between Rate and 31P Nuclear Magnetic Resonance Shift

Hammond, Philip J.,Scott, Graham,Hall, C. Dennis

, p. 205 - 210 (2007/10/02)

The reactions of a variety of 1-X-3,4-dimethyl-Δ3-phospholens (where X=Br, Me, Ph, NMe2, SEt, H, and OR) with diethyl peroxide are described.The rates of reaction show a broad correlation with the 31P n.m.r. chemical shifts of the starting phospholens, with low field shifts corresponding to the highest reactivity.The results are discussed in terms of the biphilic mechanism for the reaction of trico-ordinate phosphorus compounds with weak ?-bonds.
