Page/Page column 15, (2008/06/13)
A novel fluorinated adamantane derivative. It is a compound represented by the formula AF(-COF)n, wherein AF means a fluorinated adamantane residue which is an n-valent group formed by removing n hydrogen atom(s) from adamantane (provided that when n is 2 or larger, then the hydrogen atoms to be removed are bonded to different carbon atoms) and in which at least one of the remaining hydrogen atoms may be replaced with a fluorine atom and the still remaining hydrogen atom(s) may be replaced with a C1-6 alkyl or fluoroalkyl group; and n is an integer of 1-4, provided that when n is 1, then the AF has at least one hydrogen atom.

The present invention provides novel compounds which are useful for the production of fluorinated adamantane derivatives excellent in etching resistance and useful as photolithographic material and so on. Namely, the present invention provides compounds represented by the following formulae (3) and (4):A(-G-Q-R)nAf(-Gf-Q-Rf)n provided that the symbols in the formula have the following meanings:A: a n-valent group having n hydrogen atoms of adamantane converted to connecting bonds, wherein hydrogen atoms not converted to connecting bonds, may be each substituted by an alkyl group,R: a fluorinated monovalent organic group,n: an integer of from 1 to 4,G: -CH2- or a single bond,Q: -COO- or -OCO-,Af: a n-valent group (A) having n hydrogen atoms bonded to carbon atoms of adamantane converted to connecting bonds, wherein hydrogen atoms not converted to connecting bonds, may be each substituted by an alkyl group, in which at least one of hydrogen atoms forming C-H bonds is substituted by a fluorine atom,Rf: a fluorinated monovalent organic group,Gf: -CF2- or a single bond.
