Substitution of fluorine by alkoxy and aryloxy groups occurs especially easily (Scheme 12). Thus, 4-(l-naphthoxy)trifluorophthalonitrile was obtained upon treatment of TFPN with equimolar amount of sodium 1-naphtolate in methanol at room temperature (71 %) [26], Reaction of TFPN with 1-adamantanol (1 2 ratio) in the presence of BuLi in THF affords 4,5-diadamantyloxy substituted dinitrile (RT, 76 %) [27], All fluorine atoms are substituted when TFPN is heated with alcohols or phenols in DMF in the presence of K2CO3 as a base [27-29], In such way, among others tetrakis(2,2,2-trifluoroethoxy)- and tetrakis(2,2,3,3,3-pentafluoropropoxy) phthalodinitriles 50a and 50b (yields >90 %) - the precursors for the fluorine-coated phthalocyanines were obtained [28, 29]. 

Among subphthalocyanines with flnoroalkyl groups dodecatrifluoroethoxy substituted derivatives are known [114], The chloro derivative [(Cl)BSubPc(C)CH2CF3)i2] 205 was obtained by a standard cyclotrimerization of 3,4,5,6-tetrakis(2,2,2-trifluoroethoxy) phthalonitrile 50a in the presence of BCI3 inp-xylene (3 h, reflux, 32 %) (Scheme 54) and its X-ray aystal structure was established (Fig. 14). 

However, the results of a 125Te-NMR spectroscopic investigation of a mixture containing tellurium tetrakis[trifluoroethoxide] and potassium trifluoroethoxide in benzene suggested that only the pentakis[trifluoroethoxy]tellurate(IV) anion is formed3.
