complexes of tungsten(VI), [WCl4CHR[C6H2(But)2O]2}] R = H (1), Me (2) are reduced by Na/Hg in the presence of PMe3 to give cis, trans-WCl2(PMe3)2CHR[C6H2(But)2O]2} R = H (3), Me (4). Reaction of [WOCl4] with the biphenols 2,2′-CHR[C6H2(But)2OH]2 in diethyl ether gives [WOCl2CHR[C6H2(But)2O]2}] R = H (5), Me (6). Similar treatment of [W(NPh)Cl4(Et2O)] gives the complex [W(NPh)Cl3(1,1′-O,OH)(2,2′-CH3CH)[4

In general, we find that controlled hydrolysis of [V(NAr)(On-Pr)3] (Ar = p-ClC6H4, p-OCNC6H4 or p-tolyl) in the presence of LH2 reproducibly led to the vanadyl complex [VO(mu-On-Pr)L]2 x 2(MeCN) (7), in which the n-propoxide bridges

A process for synthesizing a quinonediazide ester is disclosed in which the esterification reaction of a polyhydroxy compound with 1,2-naphthoquinonediazide-5-(and/or -4-)sulfonyl chloride is carried out in the presence of a base catalyst comprising a basic compound represented by formula (I) or (II):
wherein R₁ to R₁₅ are defined in the disclosure. A positive working photoresist containing the ester is also disclosed. The process is capable of highly selectively yielding the desired photosensitive material containing specific unreacted hydroxyl group(s). The photoresist has high resolving power with reduced film thickness dependence of the resolving power, is less apt to leave a development residue, and has excellent storage stability for prolonged period of time.
