✦ Synopsis

The potassium fluoroborates K[RCF=CFBF 3 ] (R = F, Cl (cis-/trans-mixture), trans-C 4 F 9 , cis-C 2 F 5 , cis-C 6 F 13 , trans-C 4 H 9 , trans-C 6 H 5 ) were prepared by fluoridation (methoxide-fluoride substitution with K[HF 2 ]) of RCF=CFB(OMe) 2 and Li[RCF=CFB(OMe) 3 ] which were obtained from RCF=CFLi and B(OMe) 3 . The K[RCF=CFBF 3 ] salts were characterized by their 1 H, 11 B, 19 F NMR and IR spectra.

## Experimental Synthesis of Gels: The gels used in this work were synthesized from acrylic acid and acryloyl derivatives of amino acids that contain a hydrophobic alkyl chain (of length = n) and a terminal hydrophilic carboxyl group [13]. Specifically we have used acrylic acid (AAC, n = 0), acryl

The synthesis of three novel porphyrins (that are models for mesoporphyrin) requires the synthesis of eight new pyrroles, one new alkyl-3-oxohexanoate and two new dipyrromethanes. The new porphyrin free bases have hydrophobic substitution patterns different from that in mesoporphyrin. We are seeking
