The title compound 4 is formed in fair yield in addition to the oligomers of isobutene during synthesis of 3-tert-butyl-2,4-pentanedione (2) from 2,4-pentanedione (1) with tert-butylalcohol and perchloric acid in nitromethane.Acid-catalyzed condensation of 1 with isooctene 5 is discovered to be responsible for the formation of 4.This reaction yields other meta-neopentyl-substituted benzene derivatives (19,20,21) with several β-diketones.

PF5 reacts with Me3Si(But)NPF2(E) (E = lone electron pair or OC(CF3)2C(CF3)2O) to give products whose formation can be rationalised in terms of assuming the decomposition of the intermediates F4PN(But)PF2(E) into ButF and F3P=N-PF2(E).But, in the presence of PF5, trimerises to give a 1:1 mixture of tri-iso-butene isomers.During this reaction HF is formed, giving rise to additional Si-N and P-N bond cleavage reactions in which the compounds ButNHPF2, F3P(E), ButNH3(+)PF6(-) and NH4(+)PF6(-) are formed. - Key words: N-trimethylsilyl-N-tert-butylaminodifluorophosphine, 2,2-Difluoro-2(N-trimethylsilyl-N-tert-butylamino)-4,4,5,5-tetrakis(trifluoromethyl)-1,3,2λ5-dioxaphospholane, 1:1 Mixture of Tri-isobutene Isomers
