Organic halides as cationic initiators: Organic halides as cationic initiators. Burgess, F. J.; Cunliffe, A. V.; Richards, D. H.; Thompson D. (Propellants Explos. Rocket Motor Establ., Minist.Chemical with cas number 109-99-9 also plays role. Def., Waltham Abbey, Engl.). Polymer, 19(3), 334-40 (English) 1978. CODEN: POLMAG. ISSN: 0032-3861. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) The reaction of various org. halides with AgPF6 or AgClO4 in THF [109-99-9] was studied to det. their efficiencies as polymn. initiators. The reactivities of alkyl halides towards Ag salts in THF to generate cationic initiators were in the order F < Cl < Br < I and alkyl < allyl ~ benzyl. Under controlled conditions difunctional living polyTHF was formed with p-xylylene dibromide [623-24-5] or BrCH2CH:CHCH2Br [6974-12-5] and monofunctional products were formed with monohalides. CH2:CHCH2Br [106-95-6] and p-methylbenzyl bromide [104-81-4] on reaction with AgClO4 initiated THF polymn. by an addn. mechanism, whereas with Me2CHI [75-30-9] at room temp. ~10% proton transfer occurred. .Some commonly used reagents like 109-99-9 is used in this experiment..

A convenient method for replacing the N-methyl group of morphine, codeine, and thebaine by other alkyl groups: A convenient method for replacing the N-methyl group of morphine, codeine, and thebaine by other alkyl groups. Manoharan, Thomas Samuel; Madyastha, Kattigari Madhava; Singh, Bajrang Bali; Bhatnagar, Surendra P.; Weiss, Ulrich (Dep. Org. Chem., Indian Inst.There are some reagents with their cas registry numbers 75-30-9 and 88840-41-9 are used in this study. Sci., Bangalore 560 012, India). Synthesis, (10), 809-12 (English) 1983. CODEN: SYNTBF. ISSN: 0039-7881. DOCUMENT TYPE: Journal CA Section: 31 (Alkaloids) The N-Me group of the title compds. was replaced by quaternization with alkyl halides followed by selective removal of the Me group with a nucleophile. Thus, morphine (I, R = Me) was treated with PrI to give the quaternary iodide, which was treated with PbSNa to give I (R = Pr). .
