15573-31-6 Usage
General Description
N-PROPYLDICHLOROPHOSPHINE is a chemical compound with the formula (C3H7)PCl2. It is a colorless liquid with a pungent odor, and it is commonly used as a reagent in organic synthesis to introduce the phosphorus trichloride functional group into organic molecules. N-PROPYLDICHLOROPHOSPHINE is highly reactive and must be handled with caution, as it can react vigorously with water, oxygen, and other compounds. It is also a potent acetylcholinesterase inhibitor, making it toxic to the nervous system and potentially dangerous if mishandled. Due to its reactivity and toxicity, proper safety precautions should be taken when working with N-PROPYLDICHLOROPHOSPHINE.
Check Digit Verification of cas no
The CAS Registry Mumber 15573-31-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,7 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15573-31:
(7*1)+(6*5)+(5*5)+(4*7)+(3*3)+(2*3)+(1*1)=106
106 % 10 = 6
So 15573-31-6 is a valid CAS Registry Number.

Synthesis, X-ray structures and chemistry of enantiomerically pure 10,11-dihydro-5-phenyl-5H-dibenzo[b,f]phosphepine 5-oxides

Several phosphepine oxides were synthesised in optically pure form. Sharpless asymmetric dihydroxylation was used to introduce the chiral centres in all cases. Ring closure was achieved using either PhPCl2 or PrPCl2 together with a double nucleophile generated by either a double ortho-lithiation or double bromine-lithium exchange. The X-ray crystal structures of three phosphepine oxides illustrate their different conformations. The NMR spectra of several phosphepine oxides are described as is the chemistry which is shown to differ from that of acyclic phosphine oxides.
