p-Styryldiethylphosphine. Allen, James D. (Phillips Petroleum Co., USA). U.S. US 3998887 21 Dec 1976, 7 pp. Division of U.S. 3,847,997. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07F009-50. NCL: 260606500P. APPLICATION: US 69-832729 12 Jun 1969. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 23 Hydroformylation of 2-hexene [592-43-8] to alcs. and aldehydes was accomplished in the presence of a catalyst comprising dicobalt octacarbonyl [10210-68-1] and divinylbenzene-p-styryldiethylphosphine [55462-81-2] or divinylbenzene-p-styryldiphenylphosphine copolymer [55355-33-4]. The copolymers can also be used to remove catalyst residues from hydroformylation reaction effluent streams. The p-styryldiethylphosphine (I) [46186-07-6] was prepd. 10210-68-1 and 592-43-8 which are cas registry numbers of substances are two of reagents here. by Grignard reaction of p-chlorostyrene [1073-67-2] with diethylchlorophosphine [686-69-1]. I was copolymd. with divinylbenzene in the presence of AIBN in refluxing C6H6 under N. .

Reactions of trimethylsilyl vinyl ethers with phosphorus acid chlorides

Reactions of trimethylsilyl vinyl ethers with phosphorus acid chlorides. Lazukina, L. A.; Kolodyazhnyi, O. I.; Pesotskaya, G. V.; Kukhar, V. P.Some commonly used reagents like 686-69-1 and 61211-64-1 are used in this experiment. (Inst. Org. Khim., Kiev, USSR). Zh. Obshch. Khim., 46(9), 2006-11 (Russian) 1976. CODEN: ZOKHA4. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Reaction of O-silylated enols, e.g. CH2:CPhOSiMe3, Me3SiO(EtO)C:CHCO2Et (I), react with P(III) and P(V) chloro compds., and with PCl5 to give O or C-phosphorylated products depending on the type of enol and P compd. used. P(V) chloro compds. and PCl5 react primarily with the O atom whereas P(III) with the C. Thus, reaction of I with Et2PCl gave 40% EtPCH(CO2Et)2 whereas with (EtO)2P(O)Cl it gave (EtO)2PO2C(OEt):CHCO2Et. .
