What is Trimethylstannylboranes—inverse detection of broad ^119^Sn NMR signals in solution and solid‐state ^119^Sn cross‐polarization magic angle spinning NMR about?

## Abstract Extremely broad ^119^Sn resonances, as the result of ^1^__J__(^119^Sn,^11^B) scalar coupling, were readily detected, even for diluted samples (5 mg in 0.5 ml of C~6~D~6~), via inverse two‐dimensional ^1^H{^119^Sn} NMR experiments. Two bis(amino)trimethylstannylboranes and four dialkylaminobis(trimethylstannyl)boranes were studied. The reaction between diisopropylaminobis(trimethylstannyl)borane and trimethoxyborane was monitored by the same technique, leading to the detection of diisopropylaminomethoxytrimethylstannylborane and dimethoxytrimethylstannylborane as reaction products. Crystalline dicyclohexylaminobis(trimethylstannyl)borane was studied by ^119^Sn CP/MAS NMR. In spite of the proximity of ^119^Sn to the quadrupolar ^11^B nucleus, meaningful spectra could be obtained in a short time (≤ 2 h).
