Synthesis and conversions of dimethylphenyl(propargyloxy)silane

Synthesis and conversions of dimethylphenyl(propargyloxy)silane. Habib, Rahman Tuhi; Karaev, S. F.; Askerov, M. E.; Akhundov, E. A. (Azerb. Inst. Neft. Khim., Baku, USSR). Azerb. Khim. Zh., (3), 74-7 (Russian) 1983. 50-00-0 and 74-96-4 which are cas registry numbers of chemicals are mentioned. CODEN: AZKZAU. ISSN: 0005-2531. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) HCYCCH2OSiMe2Ph (I) was prepd. in 60% yield by treating CHYCCH2OH with PhMe2SiCl in the presence of pyridine. Some reactions of I were studied. Thus, aminomethylation of I with HCHO and R2NH (R2N = Et2N, Bu2N, piperidino) gave 41-49% PhSiMe2OCH2CYCCH2NR2. .

Oxidative addition of rhodium to alkane carbon-hydrogen bonds: enhancement in selectivity and alkyl group functionalization

Oxidative addition of rhodium to alkane carbon-hydrogen bonds: enhancement in selectivity and alkyl group functionalization. Periana, Roy A.; Bergman, Robert G. (Dep. Chem.There are some reagents with their cas registry numbers 74-96-4 and 88825-28-9 are used in this study., Univ. California, Berkeley, CA 94720, USA). Organometallics, 3(3), 508-10 (English) 1984. CODEN: ORGND7. ISSN: 0276-7333. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 75 UV irradn. of (h5-C5Me5)Rh(PMe3)H2 (C5Me5 = pentamethylcyclopentadienyl) in alkanes below -30° gave (h5-C5Me5)RhPMe3(R)(H) (I; R = Et, Pr, cyclopropyl) with significantly greater selectivity toward different C-H bonds than for the Ir analog. Treatment of the thermally labile complexes I (R = Et, Pr, cyclopropyl) with CHBr3 gave the corresponding halides (h5-C5Me5)RhPMe3(R)(Br) (II) which reacted with Br at 25° to give (h5-C5Me5)RhPMe3Br2 and RBr (R = Et, Pr). The x-ray crystal structure of II (R = cyclopropyl) was detd. .
